Since you are confirmed Orthodox and married a Greek Orthodox, the Orthodox Church requires that any children you may have should be baptized Orthodox. Also, as an Orthodox, you are not allowed to baptize your nephew or any other person in a catholic church. From the Catholic point of view, unless your nephew is to be reared a Catholic, he may not be baptized in the Catholic Church. If he is to be reared Catholic, either by his parents or godparents, the Church will receive him. No you are GREEK orthodox u must not I reapeat not baptisma your child at a catholic church.
