Customs
Hidden practices
To practice Judaism in New Spain was to risk one's life. The judaizantes knew this, and yet they maintained in secret the customs that defined them as a people. Faith was lived behind closed doors, in everyday gestures that a Christian neighbor might never notice, but that carried profound and non-negotiable meaning for the family.
The clandestinity was not accidental but systematic. Over generations, crypto-Jews developed a set of strategies to practice their faith without detection: shifted schedules, protected spaces within the home, coded language, and a dual liturgy that allowed them to comply formally with Catholicism while privately observing the precepts of Mosaic law. What is extraordinary is not that many were discovered — that was inevitable under a surveillance system as effective as the Inquisition — but that so many managed to maintain these practices for generations without being denounced.
The Sabbath
Sabbath observance was the most widespread practice and also the most dangerous, because it was the most visible. On Friday nights, candles were lit — the oldest gesture of domestic Judaism. During the period of the United Crown, most crypto-Jews tried to comply with the commandments of the Torah. All observed the Sabbath, though with forced adaptations: men went to work to avoid drawing attention, and women pretended to be sewing or embroidering when they were in fact keeping the sacred rest.
Candle-lighting was particularly risky. The Inquisition knew it as a sign of Judaism, and neighbors could notice. Some families lit candles inside wardrobes or in interior rooms without windows. Others placed them inside clay pots to hide the light. In certain households, women lit candles in the cellar or the inner kitchen, far from any window that might reveal the light to a curious passerby. Inquisitorial files record case after case in which a servant testified to having seen the lady of the house light candles on Fridays, wearing clean clothes with the table set differently from the rest of the week.
Sabbath preparations began long before the candle-lighting. Women prepared Saturday's food on Friday afternoon, so they would not have to cook during the day of rest. Dishes were kept warm over low coals or in tightly sealed pots — a practice reminiscent of the Sephardic hamín or adafina, the stew left to cook slowly from Friday evening to be eaten on Saturday. In New Spain, this stew was adapted with local ingredients, but the logic was the same: food prepared in advance to honor the Sabbath rest.
Saturday rest also had less obvious dimensions. Some families avoided sewing, weaving, or performing any manual labor that day. Children received clean clothes on Friday afternoon. Women bathed and changed their dress. These gestures, individually innocuous, formed a pattern that an experienced inquisitor could recognize — and that an attentive neighbor could report.
Dietary laws
Avoiding pork was one of the signs the Inquisition most insistently looked for in its interrogations. The judaizantes maintained the dietary restrictions inherited from Mosaic law, adapting them to an environment where any difference at the dinner table could arouse suspicion among neighbors, servants, or business partners. Some families bought pork but secretly discarded it, or cooked it only for guests while the family ate something else.
The laws of kashrut went far beyond pork. Crypto-Jews who maintained rigorous observance also avoided shellfish and fish without scales, did not mix meat with dairy, and carefully drained the blood from meat before cooking — cutting the veins and suet, washing the meat repeatedly and salting it to extract the blood. This practice, known as porgado or "purging the meat," was one of the most telltale signs because it required visible processing that any servant could observe and report to the Holy Office.
The inquisitors knew what to ask. During interrogations, they posed detailed questions about the accused's eating habits: what did they cook? How did they prepare meat? What did they do with the fat? Did they eat pork? And their parents? And their grandparents? The answers to these questions, cross-referenced with the testimony of servants, neighbors, and other family members already prosecuted, allowed inquisitors to build a dietary profile that served as evidence of Judaism.
Some families developed ingenious strategies to maintain dietary restrictions without raising suspicion. They bought pork at market — so neighbors would see them do it — but gave it to servants or secretly discarded it. Other families explained their diet as the result of health problems: the doctor had forbidden pork, they said, or they had a delicate stomach. In the cattle-ranching regions of the north, where beef and kid goat were abundant, the absence of pork at the table was less conspicuous than in the cities of central Mexico, where lard was the universal cooking fat.
Circumcision
Circumcision was practiced despite the enormous risk it represented — a physical mark that could be discovered at any moment and constituted irrefutable proof of Judaism before the Santo Oficio. Not all practiced it: the danger was such that many families abandoned it, preserving other less detectable practices instead.
Those who maintained it did so with extreme care. Circumcision was performed privately, without public ceremony, and often not on the eighth day as Jewish tradition prescribes but later, when the child was old enough for the wound to be mistaken for an accident. Some inquisitorial files record cases in which the accused explained their circumcision as the result of a necessary medical operation — a phimosis, an infection — hoping the explanation would be accepted.
Circumcision was also the practice that most divided crypto-Jewish families. The most observant considered it indispensable — the covenant of Abraham, the irrevocable mark of the alliance with God. The more cautious argued that risking the life of the entire family for a physical mark was imprudent when other forms of observance — the Sabbath, dietary laws, fasting — could be maintained without leaving bodily evidence. This debate, documented in inquisitorial testimonies, reflects the permanent tension between fidelity to Jewish law and the need to survive in a hostile environment.
Mourning rites
Funeral practices revealed the persistence of an ancient tradition. The judaizantes covered mirrors during mourning, following the Jewish custom of shivah. They placed stones on graves instead of flowers — a gesture that to this day marks Jewish cemeteries worldwide. They washed the body of the deceased with water and wrapped it in a clean shroud, practices that inquisitors learned to recognize as signs of Judaism.
The ritual washing of the body — the taharah — was particularly revealing. Crypto-Jews insisted on washing the deceased themselves, rather than leaving it to the Catholic funerary confraternities. They dressed the body in clean linen garments, sometimes new, and placed it in the coffin facing east — toward Jerusalem. Some families cut the deceased's nails and kept the clippings, a practice documented in the Sephardic Jewish tradition that inquisitors learned to look for.
Mourning also followed Jewish patterns. Bereaved families sat on the floor or on low chairs during the first days, ate hard-boiled eggs — a symbol of mourning in Jewish tradition — and received visits from other converso families who brought prepared food. Mirrors were covered with dark cloths, and in some homes all water contained in vessels was poured out, a custom that Jewish tradition associates with death.
Burial practices also showed particularities. When possible, converso families preferred to bury their dead in virgin soil, not in the stacked niches of churches. Some files record that converso families dug graves deeper than normal, or placed small bags of earth brought from some significant location next to the body — an echo of the tradition of burying with soil from the Holy Land.
The dreidel and other traces
Among documented practices, playing with a four-sided top also appears — the dreidel or sevivon, an object associated with Hanukkah. Seen in isolation, any of these customs could be attributed to other causes. But seen together — the Friday candles, the avoidance of pork, the covered mirrors, the stones on graves — they formed an unmistakable mosaic of Jewish identity lived in hiding.
Other traces appear scattered through the files: families who kept amulets with Hebrew inscriptions, women who recited prayers in a language that was neither Spanish nor Latin, men who turned to face east when praying, children who used secret names different from their Christian baptismal name. Luis de Carvajal the Younger, for example, was known in the inner circle of judaizantes as Joseph Lumbroso — a name that reflected his true religious identity.
The practice of sweeping inward — never toward the door — appears in several testimonies as a custom that converso families maintained even though many of their members could not explain why. In Jewish tradition, sweeping outward can be interpreted as sweeping good fortune out of the house. That this practice survived for centuries, transmitted as a domestic habit without theological explanation, is one of the most striking examples of how crypto-Judaism transformed from conscious religion into unconscious family custom.
Festivals and fasts
The crypto-Jews of New Spain attempted to maintain the Jewish liturgical calendar as far as possible, though clandestinity inevitably distorted many practices. The Great Fast — Yom Kippur — was the most sacred observance and the most dangerous: an entire day without eating or drinking was hard to hide from servants and neighbors. Some families feigned illness that day; others fasted partially, eating only in private after nightfall.
The Yom Kippur fast carried a particular emotional weight for crypto-Jews. It was the day on which forgiveness was sought — and for those who lived pretending to be what they were not, the Day of Atonement acquired a meaning that transcended the liturgy. Inquisitorial files record that some families gathered at the home of the eldest member of the community to fast together, praying in low voices prayers they barely remembered. Others fasted alone, each in their own home, not even knowing whether other members of the extended family still maintained the practice.
Passover — Pesach — was observed by avoiding leavened bread during the designated days. Families prepared corn tortillas or unleavened bread in secret, explaining it to outsiders as a culinary preference. Some more observant families carried out a special cleaning of the house before Pesach, eliminating all traces of leaven — the bedikat chametz — which they disguised as a general spring cleaning. The Passover meal, when it was celebrated, was a reduced and adapted version of the seder: bitter herbs, unleavened bread, and the narration — increasingly fragmentary with each generation — of the exodus from Egypt.
The Feast of Tabernacles — Sukkot — and Purim left less of a documentary trail, but inquisitorial interrogations reveal that some families attempted to maintain these celebrations, even if in fragmentary form and increasingly distant from the original liturgy. The Feast of Esther — Purim — survived in some families as a fast in honor of Queen Esther, a biblical figure who resonated deeply with crypto-Jews: she too had hidden her Jewish identity to survive in a hostile court.
Over generations, the liturgical calendar was simplified until only its most basic elements remained. Many families preserved only two observances: the one-day fast (Yom Kippur, sometimes confused with the Fast of Esther) and the week without leaven (Pesach). Everything else — Sukkot, Shavuot, Rosh Hashanah, Hanukkah — was lost in the fog of generational forgetting, surviving only as vestiges: a custom without explanation, a date remembered without knowing why.
Generational transmission
The survival of crypto-Judaism across centuries depended on one fundamental mechanism: transmission from mother to children. It was women who kept the hidden faith alive. Men participated in public life, where surveillance was constant; women controlled the domestic space — the kitchen, the candles, the funeral rites — where secret religion could be practiced.
The role of women in transmitting crypto-Judaism was so central that the Inquisition explicitly recognized it. Inquisitors knew that it was mothers, grandmothers, and aunts who taught Jewish practices to the next generation. That is why interrogations insistently asked: who taught you not to eat pork? Who showed you how to light the candles? Who told you to fast? The answer, case after case, was a woman in the family.
The revelation of the family secret was a critical moment. Some families waited until children reached adolescence before revealing their true identity — a rite of passage that inquisitorial files document in harrowing detail. The young person suddenly learned that everything they had taken for granted — their name, their religion, their public identity — was a facade, and that their family's true identity was something else, something that had to be guarded on pain of death. Others transmitted customs without explaining them — children grew up lighting candles on Fridays and avoiding pork without knowing exactly why, only because "that's how it was done in the family."
With each generation, knowledge eroded. Hebrew prayers were forgotten or garbled — words lost their original pronunciation and became meaningless sounds repeated by tradition. Rituals lost their liturgical context: a family might continue lighting candles on Fridays without remembering that this was the Sabbath, or might continue avoiding pork without knowing that this obeyed Mosaic law.
What began as conscious religious practice transformed, over centuries, into "family customs" — traditions that descendants maintained without fully understanding their origin. By the eighteenth century, after several generations without contact with normative Judaism, many families preserved only fragments: an incomprehensible prayer, a food taboo, a funeral custom without explanation. This process of simultaneous erosion and persistence is what makes crypto-Judaism in New Spain an extraordinary phenomenon — and what today allows genealogists to trace converso lineages by following the traces left by customs that no one could entirely erase.
The double life
Crypto-Jews lived in permanent tension between their public identity and their private faith. In public they were devout Catholics: they attended Mass, baptized their children, married at the altar, contributed to parish works. In private they observed the Sabbath, fasted on Yom Kippur, avoided pork, and taught their children the traditions that had been taught to them.
That double life required extraordinary discipline. Any slip could arouse suspicion: a word out of place during confession, an automatic gesture when lighting candles, an unconvincing excuse for missing work on a Saturday. Crypto-Jews developed a coded vocabulary — they referred to God as "the Lord of the heavens" to avoid pronouncing names that might betray them, and used euphemisms for practices they could not name openly.
Catholic confession was one of the most dangerous moments. Crypto-Jews had to confess regularly to avoid arousing suspicion, but confession required declaring one's sins — and the practice of Judaism was, for the Church, a capital sin. Some families developed strategies: they confessed minor, invented sins, avoided the most perceptive confessors, and changed parishes when they felt a priest was beginning to ask too many questions. The most devout lived this imposture with profound anguish — forced to renounce their faith before a priest in order to continue practicing it in private.
The paranoia was justified. Servants were the most frequent informers — they had access to the interior of homes and could notice what neighbors could not see: the clean clothes on Friday, the meat washed with excessive care, the candles lit at unusual hours, the pots of food prepared in advance for Saturday. Many converso families preferred to have no servants, or kept the same domestics for generations, integrating them into the family secret. Others employed only indigenous servants, trusting that the linguistic and cultural barrier would prevent them from understanding and denouncing what they saw.
The networks of trust among crypto-Jewish families were at once their greatest strength and their greatest vulnerability. When the Inquisition captured a judaizante, interrogation under torture could extract the names of dozens of others — relatives, business partners, trusted friends — triggering chain raids that devastated entire communities. The great conspiracy of 1596 and the auto-da-fé of 1649 demonstrated the effectiveness of this method: a single informer could set in motion the destruction of an entire network.
