Make no religious distinctions among yourselves, for this would require you or others to be judges. Only the Lord is our Judge.
Do not say, “This one is Christian and that one is not.” Do not even take the label for yourself. Speak in His name by all means. That is, speak to Him. And speak of Him to others. But do not take a name to yourself that makes anyone else less of His child. The moment you call yourself Christian, you establish an artificial boundary between yourself and others who don’t choose that identity. Jesus died to make us all one. Every person belongs to Him. Therefore, religious labels create divisions among people for whom Christ died.
Don’t just eliminate these distinctions from your speech. Eliminate them from your mind. See all people as God’s children, regardless of their level of understanding.
The Lord knows all hearts. He knows whether we are truly faithful to Him or not. As to others, if we truly love Him it will become apparent to them shortly. If we have to wear a name tag that says we belong to Christ (“I’m a Christian”), maybe it’s a sign that there is not enough behavioral evidence to establish the point.
Live in such a way that you are identifying with Him – not with a group of people who say they identify with Him. A group of people did not die for you. He did.
