Charles Augustus Briggs

He was excommunicated from the Presbyterian Church for heresy due to his liberal theology regarding the Bible.

At the Union Theological Seminary, he also served as head librarian for the Burke Library.

[6][3] In 1892 Briggs was tried for heresy by the presbytery of New York, including James McCook, and acquitted.

[3][7] Some[8] have argued that General Assembly's finding of heresy was influenced, in part, by Briggs' belligerent manner and militant tone of expressions and by what his own colleagues in the Union Theological Seminary called the dogmatic and irritating nature of his inaugural address.

[6][8] After his condemnation by the Presbyterians, he turned towards Episcopalianism[9] and was ordained as a priest of the Protestant Episcopal Church in 1899.
