Question
Are there any disabilities that in modern times render an individual unfit to take part in a ritual practiced in Jewish life today, even if one wanted to?

Question
Hello, I am a convert, my wife and my daughter (8 weeks) are Jewish. I have a Gentile ex-spouse, with whom I fathered two children almost 10 years ago. My question pertains to Ezra 10:10-11 as well as the portion in the Talmud (Yevamot 23a). How does this apply to me with parental & paternal Gentile children not being a Jewish man's children, even if his seed made them. I wasn't Jewish when I conceived them, but I am now. As heartbreaking as it seems, I just want to follow halacha and do what's right by them as well.
