Sorry, but there really was once a concept that stressed "Blind Obedience" in both seminaries and convents.  It has nothing to do with life being fair or not.  Exactly how gullible do you expect people to be today?  Unfortunately, some of our hierarchs expect people to be very gullible.

If people are dedicating their lives to a way of life----they cannot take or make vows if they don't understand what they are being asked to do.

And the authority setting up this Blind Obedience, is not God.  The apostles were married.  In the early church, bishops and popes were married.   The gnostic heresy got into the Church [popes believed certain aspects of it] and it became a DISCIPLINE in the church.  It certainly was not a mandate by God.  Jesus himself could have been married, as a young Jewish man, then widowed.  We have nothing to prove or disprove this [right now].
