So I mentioned that God calls us to the unity of faith and Spirit in Ephesians 4, and that allows for some variance, since it's "the unity" and not "the uniformity." At the same time, though, God does give a list of 7 things that we have to be united on; namely that,
"There is one body and one Spirit, just as also you were called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all who is over all and through all and in all." (4-6)
From what I can tell, most people will buy into 6 of these, but shy away from baptism. Since they are listed without preference, it seems that God equates denying baptism with the same denying the Spirit, or the one God. I certainly feel free and unafraid saying that I agree with God on all 7 counts!
"For the entire Law is fulfilled in in this one word: "You shall love your neighbor as yourself."—Gal 5:14
