Do we lose focus on “loving all” if we judge other Christians – in words only?
No loss of focus here. This is part of the battle (justice – judging the house of God ).
All prophets and men of God in the Bible (including Paul) did not shy away from pointing out errors involving “believers only” which came to their attention. .
The “love all” part is proven by the fact that we don’t pass any “Judgment sentences” on them (such as request one to be disciplined from joining the music team etc when one has admitted and is sorry for his sins); Warn them of Judgment verses in the Bible only (no taking matters into our own hands). That’s all.
Remember, “correction” (not sadistic torture) is part of love too!
“in this shall all know that ye are My disciples, if ye may have Love one to another.'” (John 13:35)
