I don't think the Church really needs to consider those questions at all, because Church tradition very much holds that:

- No, machines cannot have a soul, as the soul is something we receive as beings made in the image of God. We cannot create in the same way. Therefore, machines cannot be baptized. - The machine can't be Christian because it can't receive sacraments, including baptism. - Jesus was unequivocally a savior only for humans.
