Today, the Orthodox Church in North America, as throughout the world, is characterized by her diverse ethnic and cultural expressions of "the faith once delivered to the saints."

Administratively, the churches in the New World developed as missionary dioceses or extensions of their mother churches abroad, thus resulting in several Orthodox jurisdictions in this land. The oldest of these missionary dioceses was granted ecclesiastical independence from her mother church in 1970, thereby becoming one of the fifteen autocephalous churches of the world, taking the name of the Orthodox Church in America (OCA).

The Orthodoxy in America project is an online directory of the parishes, monasteries, and seminaries of the twelve major Orthodox jurisdictions in the United States, Canada, and Mexico. It is offered as a free service of Orthodox Web Solutions.
