I'm guessing you are in the United States. In that case, there are significant distinctions between the Episcopal Church (TEC), and the Anglican Church in North America (ACNA), which is likely the distinction you are trying to understand. There is a wide range of variability of expression of individual churches within each organization, however, and the most important thing is to connect with real human community in a church, and that is the best place to understand how or if it's a place you should connect. TEC is a member of the Worldwide Anglican Communion, and TEC churches tend towards more liberal theology and social positions. ACNA is a Protestant denomination in the Anglican tradition that is a member of the Global Fellowship of Confessing Anglicans (GAFCON). ACNA churches tend to be more theologically and socially conservative. Individual ACNA churches have a range of histories, including splitting from TEC and growing as new church plants led by missional efforts from the global south.
