In stand-alone ecclesiastical provinces, the Primate is the metropolitan archbishop of the province. In national churches composed of several ecclesiastical provinces, the Primate will be senior to the metropolitan archbishops of the various provinces, and may ... be a metropolitan archbishop. In those churches which do not have a tradition of archiepiscopacy, the Primate is a bishop styled "Primus" (in the case of the Scottish Episcopal Church, "Presiding Bishop", "President-Bishop", "Prime Bishop" or simply "Primate". In the case of the Episcopal Church in the United States, which is composed of several ecclesiastical provinces, there is a Presiding Bishop who is its Primate, but the individual provinces are not led by metropolitans.
