I am cradle Episcopalian. When my husband joined my church after we were married 25 years ago, I attended the confirmation classes with him. There were 16 members in his class, my husband was Presbyterian, but the majority about 3/4 of the class was Roman Catholic. They were either in mixed marriages seeking a happy medium or they were remarried after divorce.
The local ECUA parish, where I have friends, has 3 ex Roman Catholic converts on a vestry of 7. They are poorly cathecized in anything catholic, Roman or otherwise and are always pushing for the "innovations".
I'm not surprised. The Episcopal Church is the closest to being Catholic that they can find and still be able to do the things they want to do, ie, divorce and remarry, seemingly without guilt.
