I'm a "patrilinear" Jew, only my grandfather was really jewish for halakhà. I'm proud of my jewish heritage and I follow many jewish traditions (like Kasheruth, Pesach, Yom Kippur...) From 2007 I attend a orthodox congregation in my city. I don't think one day I will make the ghiur, 'cause I have a non-jewish wife and a son, and I think that is not possible in these circumstances to convert, to "return" to judaism. So, in these day I have found my grandpa's tallit, and I don't know what do with it, I would find a significance for it. I know that is not possible to wear this in synagogue, but is possible to use it in my home for the tefillah?
Thanks, shalom, Pesach Sameach
