Officially, the difference is that the ACNA is treating the latest stages of a disease that has been allowed too long to develop. We deplore blessing of same-sex unions as much as the next fellow; but we also deplore the basic rejection of God's own authority that laid the groundwork, the earlier rebellion that made this latest symptom of ECUSAnism possible. We recognized the earlier symptoms of the fatal disease back in 1977. We knew that we had to treat it drastically by cutting out the infected organs and taking the full dose of antibiotics. But, the leaders of the ACNA have yet to detect the early symptoms, for they still accept priestesses in the church.
This confusion about sexual identity in one sacrament, ordination, was the necessary first step leading to rejection of the marriage sacrament and covenant as established by God in the creation of Man. If a woman can be ordained to a male role (a father in the household of God-see I Tim. 3), then two men can marry each other, or two women. Therefore, though we may pray for our ACNA brthren to become enlightened, we cannot join with them. They are following along the same path as the Episcopalians, only they are going at a slower pace from a further distance. The destination is the same.
This old essay, reprinted from October 2007, may help explain:
The Holy Ghost made me do it
The problem with those who are "led by the Spirit" is that they must re-imagine the Bible and disregard Tradition. To do this, they must first invent little fictions. Did you know, for example, that New Testament approves of and endorses slavery? This would have come as no small surprise to the American Abolitionists who based their movement on their Christian Faith and scripture. But, now we have the generally accepted consensus of the Revisionists. I suppose that Saint Paul, instead of teaching the right way of life to Christians who were slaves under the pagan system of Rome, should have urged a Spartacus style revolution, no doubt with the same results, instead of carrying out his mission. His failure to do so must be read as approval of slavery, if not endorsement. And, why must it be so read? To make the Revisionist argument, that's why. Obviously, these Revisionists have never read Deuteronomy 23:15, 16: "Thou shalt not deliver unto his master the servant which is escaped from his master unto thee: He shall dwell with thee, even among you, in that place which he shall choose in one of thy gates, where it liketh him best: thou shalt not oppress him." The abolitionists, however, had read it.
These allegedly Spirit led innovations teach us that God is capricious, but at least he is growing in his understanding, and so leading us to follow him in his own search for enlightenment. It took him quite a while, by another of their fictions, to figure out what to do with Gentiles in the Church (it seems that their Holy Spirit, unlike the One we know, never plans ahead). Once again, a little passage of scripture the Revisionists seem never to have read is Acts 11:17, 18. "[Peter said] Forasmuch then as God gave them the like gift as he did unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God? When they heard these things, they held their peace, and glorified God, saying, Then hath God also to the Gentiles granted repentance unto life." They confuse Peter's later flaw, as recorded in the Epistle to the Galatians when he was corrected by St. Paul, with the heresy of the "Judaizers" that sprung up even later still. They miss the fact that Paul corrected his fellow apostle on the basis of settled, revealed, doctrine already established, and that the Council in Jerusalem (Acts 15) defended and upheld that same established doctrine. But, by inventing this period of doctrinal confusion, this historical "fact" of their collective imagination, they show once again, by using scripture (in clear "Jehovah's Witness" style) that their God takes a while to figure these things out, and then leads them into the newest discovery of his limited, finite understanding, His never-ending search for truth.
So, their Holy Spirit takes them into new and unsettled territory as he matures and learns. Our Holy Ghost, however young He was on the Day of Pentecost, has become old and set in His ways. He does not approve of women's "ordination" anymore than He did when Christ bestowed Him on the Apostles. And, He does not bless same sex unions, no matter how many clergy persons do. The Revisionists have used the same arguments for women's "ordination" that they now use for Homosexualism because, they walk in the same spirit, and in the same steps. And, no, it is not the Holy Spirit.
If they are going to quote Flip Wilson, they ought to quote him verbatim.
So, you see, returning to 2011; the difference between us and the ACNA is that they have no ultimate defense against the thinking I have described above.
