The Rebordelo´s Manuscript is a book of prayers and customs of the Portuguese crypto-jewish community, written by Abraão Moisés Gaspar, on the 19th century in the village of Rebordelo, Portugal. Interestingly, some of the prayers and Minhagim prescribed in this book are held for generations among Brazilians with Portuguese ancestry. Most of these prayers and traditions are to be found in documents of the Inquisition as well. http://www.rebordelo.net/cripto-judaismo/manuscrito/doc003.htmlThus, as those prayers and traditions were commonly practiced among some crypto-jewish families for centuries, and מנהג אבותינו תורה היא, does it mean that the descendents of Portuguese cripto-jews are bound to follow the Minhagim prescribed on Rebordelo’s Manuscript?
