The People of God are the Church----96% of the laity and 4% of the clergy/hierarchy.  You keep on identifying the 4% only as the Church.  All of us have had relatives, friends, neighbors, and co-workers who have divorced.  And guess what?  We understand that very human people get married, and marriages do not always work out well.

Secondly, Jesus, as a historic human being, lived at a time---when women could be handed a writ of divorce at any time.  And SHE could not contest it.  Jesus was offering a support to the women.  If priests can be laicized and go back to the single state---why not married couples?  Both the Sacrament of Holy Orders and Matrimony are Sacraments of Service.  But apparently, the hierarchy of the church only give a way out only to the men who are priests.
