Practice meaning all the "extra" stuff catholics do, like hail Mary's. He'd be de emphasizing the importance of rituals in Christianity. Location isn't important to mainstream Christianity afaik.

Beliefs doesn't fit quite as well, I agree. He probably would have said only one belief or something. I still think he might say something like that though, de emphasizing the other beliefs Christians hold. Christian perfectionism, purgatory, gay marriage, none of those things should divide God's people. They should unite to do good things. I'm imagining all this wrapped up in a sermon on serving one's community.
