"by the usage of Christian congregations throughout the ancient world.'
I commented earlier on this phrase from the WT Article, but they are not consistent on this, apart from the books/Writings they reject totally, which were used by many in the early Churches, they reject the passage about the Woman caught in Adultery, they claim because it "is not in the earliest manuscripts", but there is evidence this passage was long used in the early Church.
Later bishops did not like it because it took away their Control, how very like JW's own G.B ! and because it was too lenient on the woman, had it been a man in the story it would have been different no doubt.
