NOBODY can make a 'coherent case' as far as you are concerned!  The Church needs change and renovation quickly, or it will die on the vine.  And we're not even speaking of reaching out in growth.  Jesus did not tell his disciples to only preach to the Chosen People---but to the entire world [which God loves].  But individuals like you---are fearful of any change, of pushing forward.  These are the times that require mercy and compassion toward the 'so-called sinners'.  And joy, kindness, gentleness from the rest of us.
