I guess I can understand the classes from that perspective. But I still think it is flat out wrong that they wanted me to commit to their specific denominations before they would baptize me. There's nothing suggested in the Bible that all catholics get salvation and all protestants don't, or vice versa. Different denominations within Christianity are still Christian, and I don't like the idea that a priest wanted to force me into being part of their denomination before he will help me. Priests, as far as I understand it, are called by God to serve His people, not called by their denominational church to only serve those within that specific church.
Catholicism is something of a special case...
It's not just about salvation. It's more about not administering sacraments to people who might be hurt by them. Remember the verse about people eating and drinking condemnation on themselves? Catholics take that to apply to all the sacraments: that they can actually hurt people who are not within the Church in a certain way. Good priests are certainly willing to help anyone in need of it. It's just that what you consider help, and what they consider to be such may sometimes differ. He would probably think it helpful to instruct you in the faith before proceeding further. There's also an issue of church structure involved...
The Catholic Church is not a denomination. It's something else - usually called a church. If you believe them, it's
the Church. The way it works is, in the beginning there was just the Church. Then some heresies popped up, like Jesus is not God, or Jesus is not human, or things like that. Then there was the Church and the heretics. At the Fourth Ecumenical Council the Copts disagreed, and then there was the Church, the heretics, and the Coptic schismatics - because their disagreement was major enough to be a big deal, but not major enough that they had a completely different understanding of God). Then some centuries went by, and other things happened, and then the Catholics and Orthodox bishops excommunicated each other. Literally, that means they're not in communion - that is, they cannot receive sacraments from each other's church, specifically Communion. So then there were the Catholic Church of the West, the Orthodox Church of the East, the Copts of North Africa, and (presumably) some heretics. Who were the schismatics is up for debate; I'm obviously biased

. Another five centuries went along; the Reformation happened. There were then the Catholic Church, the Orthodox Church, the Coptic Church, and the Protestant movement, which quickly became the Protestant denominations. Of these four groups, none of them are in communion with each other (to additionally complicate matters, not all Orthodox groups are always in communion with each other either, but I digress). Protestant denominations are usually in communion with each other by virtue of not believing it possible for a Christian to be harmed by things like receiving communion out of a state of grace. To participate in sacraments in a church one is not in communion with, it's necessary to become a member of that church.
Sorry if that was somewhat garbled...:o
