In many ways, a family is a single organism, for in truth the child has never left the parent.
When a parent’s inner convictions strengthen, the child grows as well. When a mother begins to light Shabbat candles, her children, even on the other side of the world, find light luminating their lives. If she will begin to go to the mikveh, her children will find more purity in their lives.
So too, when a child changes paths for the good and begins a new mitzvah, the parents, although unaware, find their lives also transformed.
To anonymous in Brazil Since you are from South America, I would suggest checking out your ancestry. Many people in South America were originally Jewish - they converted to Christianity during the Inquisition in order to save their lives and many fled Spain to South America; as the years passed, their families were not told about their roots. Obviously, conversion would be required because too much time has passed.
Do an online search for Conversos and you will find tons of reading material – I didn’t do a thorough search as to Brazil, but there definitely sources in Mexico and Puerto Rico. (Spanish and English sources.)
As to being a guer, many years ago when I was teaching in the shul, an Orthodox rabbi did a class for the teachers. A line he said has never left me ... "had I not been born Jewish, I would have chosen to be Jewish"; he called guers "choosing Jews". I have used the term ever since. My perspective is that a Jewish soul will always find its way home.
