This isn't a Build a Religion store is it?

[BluffTHIS!]

We conservative catholics call those type of catholics who want to pick and choose among the church's doctrines, "cafeteria catholics".

And the myriad of protestant denominations, which after splitting off the catholic church have continually split off each other, show that "build your own variety of christianity" is very popular.

They say "I don't agree with X", when they are really saying, "I don't agree with the teaching of God and His Church on X".
