George David Cummins (December 11, 1822 – June 26, 1876) was an American Anglican bishop and founder of the Reformed Episcopal Church.

[2] A tremendous reference that gets no visibility or discussion and that details the Bishop's life, attitudes, beliefs, and career are given by his wife, Alexandrine, in the Memoirs.

[4] Cummins' Evangelical theological persuasions led him to separate from the Episcopal Church, which had, in his mind, been poisoned by the ritualism of the Anglo-Catholic party.

And when he could no longer in good conscience serve the Diocese of Kentucky due to Ritualistic advances, he left the Episcopal Church.

Bishop Cummins left the Episcopal Church due to conflict with Anglo-Catholic theology, one facet of which is the insistence on Apostolical Succession for valid ordinations.
