Rules have their place.  Simple and clear rules can be helpful.  But Jesus came to fulfill the law, not to preach it.  Mark 1:15.  Let me be blunt.  It is very human and very understandable for the community to establish rules.  The rule of indissolubility is an understandable affirmation of marriage, particularly in times when the institution of marriage us under stress.  But to see Jesus with only one eye, as a rule giver, without seeing that "love of God and neighbor" are the font and measure of every rule, is to run into the ditch of idolatry.

Even the church has been tempted to this idolatry.  But at every point -- on the brink of idolatry -- the church has instead responded to the Spirit, as Jesus said it would.  Read history.  In the last post I cited the Council of Ephesus.  At Trent, the Council refused to condemn the Eastern Church, which followed Ephesus.  There are more recent examples, not the least of which is Chapter VIII of Amoris Laetitia.  Take heart in the Spirit!
