An abuse!
Another example is the freedom enjoyed by priests of the Oriental and Greek church to remain married to their wives after their ordination (see can. Aliter, dist. 31 and chap. Cum olim, de Clericis Conjugatis). Considering that this practice was at variance neither with divine nor natural law, but only with Church discipline, the popes judged it right to tolerate this custom, which flourished among Greeks and Orientals, rather than to forbid it by their apostolic authority, to avoid giving them a pretext to abandon unity. So does Arcudius assess the matter (Concordia bk. 7, chap. 33). (Pope Benedict XIV, Allatae Sunt, 22)
the popes judged it right to tolerate this custom, which flourished among Greeks and Orientals, rather than to forbid it by their apostolic authority, to avoid giving them a pretext to abandon unity.
In other words, the Popes tolerate the abuse rather than give the Easterns a false reason to schism.
The Latin rite priests hold the line by which all others are measured.(even in this abysmal day) Just as the Protestants of the early 20th Century looked far more "Catholic" in order to look legitimate when measured against the Catholic Church. Now, when Vatican II came along and the Churchmen wanted to join the world, everything went to pot in the Church and without. As the Catholic Church goes, so goes the world.
