You define Christian by whether or not the person adheres to a given set of doctrines.
I define Christian by whether or not the person strives to follow Christ.
There is the disconnect.
OK , I’m Elvis
32 Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.It's black and white what Jesus says makes you a Christian (not necessarily a good Christian, but a Christian), where does anyone get off deciding they can tell Jesus who he will call his own? There are four main sects of Buddhism, they don't go around saying the others aren't Buddhist, Hindus don't call other Hindus pagans Taoist don't argue over who's ancestor is better, it's just the Christians who want to say others are not of their faith. Faith; that is what it comes down to who do you believe in. We believe in Jesus Christ, born of Mary, healed the sick, cleansed the lepers, walked on water Crucified on the Cross, that Jesus, yet some want to say we believe in a different Jesus than they do. well if they do not believe in that Jesus, but some guy from Mexico they could be right. If they are saying that because of our different beliefs about this same Jesus, then they are being disingenuous, playing loose with the truth, or have a casual relationship with reality, take your pick.
33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.
