But it is more black and white than Jesus gave us. God gave the 10 commandments, and the command to love God and one another, the Catholic (and many other Christian churches) give many, many more rules than that.
I am not saying that your way is wrong (though I do think that saying there is only ONE way, and it is the Catholic way, is wrong), I am saying that I think there can be more than one right way.
numbers, when I was baptised as an adult in 2005, I was dunked in a swimming pool! We got in the pool (clothed) and then the pastor said all the words etc, and we agreed and they put our heads under. In Beijing, we have to improvise

I had to go to several classes before I was allowed (and there were several who, at the end of each class, decided they weren't ready). I was already baptised and gone through the whole process in Catholicism, but just like God told bek to leave Protestantism, he told me to leave Catholicism and explore. I explored a lot, had an overwhelming experience when I was 18 and became run-of-the-mill Christian. I have been to lots of different services, I love Midnight Mass (Anglican) at Christmas, love concert-like services when I feel like worshipping with a big group, adore Easter services, and get a lot out of Good Friday services, too. I don't go to church every week (in fact, hardly at all now), but I do have interfaith group once a week, and a Bible study with fellow Christians, as well as a brunch on Sunday. I feel I give and get a lot more for and from God from these activities than I ever got out of attending a church service.
