Your tagline would seem to make you un-Christian. As a matter of fact, it's downright offensive.
I am a Christian.
Very serious one, in fact. Converted from Judaism (flirted with Orthodoxy, in fact, for several years, lived in Israel). My faith that Jesus was/is the Christ is so strong I pretty well alienated my whole family.
And, curiously, I've gotten about 100 posts, public and private, mainly from Christians, who love my tagline because they, too, are disgusted by the holier-than-thou attitude of so many at FR.
As a Christian, I KNOW I am no better, in God's eyes than anyone, and it is only through grace that I am a marginally acceptable human being.
Hence the constant rib of holier-than-thos. And hence the tagline.
I am sorry you are offended, but it stands.
