I would be gone in a NY minute and NEVER look back. I do not understand why it even seems like a hard decision to make. Some things are just obviously Biblically wrong and as a Christian I would not waste one once of worrying or sadness in leaving a place that preached a lie. Cause we all know who the father of the LIE is.
It's clear you're not a cradle Anglican. I know from experience just how hard it can be to leave.
Part of the issue is really the remote nature of the bishops and the denomination organization to individual churches.
Especially for cradle-to-grave Anglicans (I am not one) its very hard to leave a good church, which is orthodox in its teaching--since in ones weekly connection to the Church, that congregation is all you see. We read in the news about what the Bishops are doing--but the particular TEC church I attend doesn't see an acting bishop but once or twice a year.
So here your church is struggling to be faithful, while the high-and-mighty bishops do their thing on a different plane than your normal life. What to do too--leaving beautiful churches built by local money, along with the grave-sites of your ancestors???
Another thing too, which I hear precious little of among the outside critics of the orthodox in the TEC--what example in the Bible do we have of the prophets, or Jesus or the disciples of leaving the heretical Jewish religion?
Even after Jesus was crucified by its leadership (only to rise again!) the disciples continued to teach and pray at the Temple. Murdering God is even more serious than homosexuality in my book....but only when utterly forced to, was there any break with the Jewish religion.
Now many TEC priests and congregations are being forced out by the revisionists--so I don't blame them--however there must be a place for faithful prophets, who suffer persecution, in TEC--as long as the heretics allow it.
