If I may interject, my maiden name was Arroyo. My cousin did a geneology of our family and came to the conclusions about being Jewish. Your comment though about an affirmation of being a Jew because your family walked out on a sermon wouldn't necessarilly determine them as Jewish because many wise persons Jewish or not have been disallusioned with false religion, not because of any previous beliefs but because the church just did not practice true Christianity and stick to what the Bible (God's word) says. The Catholic church is rather full of man-made doctrine and belies its claim to what real Christianity is about as are all, but one religion.
