I an familiar with the Affirmation of St. Louis; most of the so-called "continuing" Anglican churches got their start here, including the one I currently belong to, the Anglican Province of America. There are a number of others.
The 39 Articles which I refer to can be found at or near the back of every BCP since the beginning. Some of them may or may not have been written the way they are for no other reason than to be anti-Rome. I couldn't say. There is also one Article on the error of conducting a service in a language not understood by the people, i.e. Latin.
Perhaps what you are actually using is the Anglican Rite Liturgy which draws much from the BCP but with certain elements of the Roman Catholic mass blended in - that may be a poor way of phrasing it. Forgive me, I don't wish to offend anyone. From what I can tell from reading it, the Anglican Rite Eucharist is a beautiful service.
The ACC has one of those distinctions that has been difficult to explain to people without going into a great deal of history. The Romans lump the ACC in with the ECUSA and say we are still mad about King Henry VIII...and the Protestants don't like us because we are too Catholic in our upholding of the Transubstatiation. I have heard one of our elders in our church talk about consubstatiation, but mainly as a point of reference. From the three years that I have attended this church, and from talking to the priest, Transubstantiation is unquestioned by the ACC.
No offense taken however!! i was glad to converse with you!
