There no such thing as a christian that is not traditional. If you don’t believe in the Word of God and the literal truths of scripture, you might be something, but you’re not a christian!
Yes there is; it is a person who has genuinely accepted the person salvational offer of Jesus Christ.
THEN the improvement in life begins. Some people in that situation may look very untraditional on the surface. But the Lord knows that this is only the surface. They will not be excused, but they will by the Lord’s promise be forgiven and saved.
Talk in the vein that we must make ourselves Christians is very vain and very misleading. All we can do is find ourselves learning to assent to the reach of the Lord.
