Maybe they got it from the bible...The apostles were told to go to all nations...But for the most part in the book of Acts, most of 'em stay around Jerusalem...
So either they disobeyed God or some here are having trouble with the word nations...
But then they were told to baptize in the name of the Father, the Son and the Holy Spirit...But they didn't do that either...They baptized is the name of Jesus...
It must be the meds. I have no idea what you're saying.
