Paul commanded it. That would be unity in word and deed. Was Jesus praying for idolatry. Doctor Shelly, real religious unity consists in teaching and doing the same things. We can meet, eat, pray, weep, touch, and be sentimental till the cows come home, but that will not unite us.
Meaningful unity comes from walking in the light.
But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus his Son cleanseth us from all sin.
