"The apostle teaches that while we should manifest Christian courtesy we are authorized to deal in plain terms with sin and sinners; that this is not inconsistent with true charity. “Whosoever committeth sin,” he writes, “transgresseth also the law: for sin is the transgression of the law. And ye know that He was manifested to take away our sins; and in Him is no sin. Whosoever abideth in Him sinneth not: whosoever sinneth hath not seen Him, neither known Him.” AA 555.1"
