Allen and Jones actually separated from the Methodist Episcopal church which was a Methodist denomination at the time.
Formed the Free African Society which is where they clashed on direction.
Allen wanted to stay in the Methodist Episcopal denomination whereas Jones wanted to split from the church altogether.
Allen formed the African Methodist Episcopal Church.
Jones founded the African Protestant Episcopal Church. The “African Protestant” is not a separate offshoot of the Episcopal Church, but is an informal title that distinguishes and connects, as a web, the all-black congregations of the Episcopal Church found in every major city nationally. So for instance, Jones founded St. Thomas in Philly, the sister congregations to that church in, let’s say Chicago, is St. Thomas and St. Edmund’s, or in Boston, St. Cyprian.
And yeah, as you mentioned, there were definitely class stratifications, hence the “we were Episc....”.
But there were also class stratification within denominations themselves. So at least for the mainline churches, you can have an upper class Baptist Church or Methodist Church in a city, too. Most of the time, these were the oldest congregations of each respective church. For instance, in Manhattan, there is Abyssinian Baptist Church. A lot of prominent folks went there.
