Here is part of the problem:  In line with Vatican II, "[Fr. James Martin]staunchly insists he seeks no change" when in fact, he seeks deep change in the very "tolerance" he prescribes.  Fr. Martin seeks to crack the door open on sexual doctrine, somewhat as Martin Luther sought deep change in the doctrine that one could purchase salvation with prayer and almsgiving.

Changing doctrine, even cracking the door slightly open to doctrinal change, is something even Pope Francis won't touch, as evidenced by his pastoral defense of the changes he is trying to implement in the Church.

It may be time in the Church for Vatican II-oriented clergy to look at canonically approved structures in the universal Church that allow more room for a post-Vatican II implementation...structures such as prelature, ordinariate, with eventually, perhaps, a post-Vatican II Rite/Church in union with Rome and the Eastern Rite Churches.
