Marx's objective is clear and a statement to this effect was inserted in the interim relatio of the 2014 Extraordinary Synod on the Family; namely that the Church should recognize the "value" in "committed" same sex relationships. This caused an uproar at the time but it's clear that Marx is not backing off. He appears to have little fear of censure or disciplinary action and it's easy to see why. Francis' now infamous "who am I to judge?" comment was in response to a question about homosexuals in the priesthood.
There is an orchestrated effort underway to make the Church lavender friendly and all the demonizing of "rigidity" and "doctors of the law" which Francis has been spewing for three years now, is directed principally to this end. The lines are being blurred for heterosexual marriage first, regarding what is and is not a "valid" union but it's a forerunner of bigger things to come.
It is quite apparent the Catholic Church is moving in a slow yet determined manner to accept the practice of homosexuality.
Among other consequences, the Catholic Church must now completely renounce their opposition to birth control. If the Catholic Church holds that birth control is a sinful act because it denies the process of procreation, then the church can no longer oppose birth control because all homosexual acts engage in a sexual practice that denies the process of procreation.
Now that the Catholic Church is actively undertaking steps to separate themselves from immutable truth they have engaged with certainty the perpetual motion of their own self devolution.
I call upon all those who love the Lord Jesus Christ to come out from any organization that has set upon idolatry.
