Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
(a) I applaud the Episcopalians, the Anglicans, and many other such Protestant groups for their sincere and wonderful efforts towards mutual tolerance, inclusion, and fellowship between diverse communities. Christ asked us all to love each other, to fellowship with each other, aside from self-righteous distinctions. That means that folks outside Christianity need to be humble enough to explore it, and Christians need to be humble enough to avoid pointing fingers all the time.
However, that being said
(b) Surely we can develop an attitude of tolerance, mutual respect, and fellowship without inherently changing the Church. Why do transgender folks needs to be ordained in the first place? Being laity is simply not good enough? Pride and vanity are not good traits for clergy. The same with Sacramental gay marriage (I support civil/secular gay marriage, just not within the Church), why does homosexual marriage need to be Sacramentally blessed and ordained? If homosexual folks want to go to Church, they have to expect Church to change them, like it does the rest of us, and not to change the Church. That is precisely the problem with Protestantism, its ontology is quite literally backwards. WE ARE ALL SINNERS, PERIOD. There is simply no way around that. We in the Church simply then have NO RIGHT to cast stones or point fingers at other peoples' sins, be they inside or outside the Church. We come to Church to be changed, renewed, reconciled by changing ourselves every day for God. Protestants on the other hand, always seem more content to change their churches then to change themselves.
That is the problem. So I am not concerned with our Protestant churches change and evolve, as these by their ideology are inherently unstable. We in the Church need to learn to be more socially inclusive, more tolerant, more respectful, more loving to those outside the Church, especially those who are homosexual or just heterosexually promiscuous (i.e., in relationships but not married) because it is not our business to force their lives to adjust to us. Only God can do that, We however as a supportive community could do a lot better to help people grow, mature, and heal through love. We should be nice and open to each other, embracing and accepting especially of our faults. Homosexuals are sinners, true, but we can't close the door in their faces for that. So we need to create an environment that is more inviting. However, I think those who change their churches in this process are going too fast. We can change our attitude, our approach, without changing our Church. We can be tolerant and loving and inviting in our interactions with folks, without having to change our own structure. After all, I rarely here homosexuality or adultery brought up in the Church in the first place, so why do we throw it around in other peoples' faces as if it were a daily issue in our parishes. The simple truth is its not, and we could afford then to just be a bit nicer, though I would say that folks from the OP churches are being just a bit too
