Grant was born in Boston and was educated at Harvard University (AB, 1883; AM, 1886) and at the Episcopal Theological School in Cambridge, Massachusetts (BD, 1886).

He became known for his support of socialism and for his "forum" for the expression of views on labor and living conditions.

Advocates of all political and social doctrines were permitted to speak freely.

This was widely criticized and finally, in 1923, following action taken by Bishop William T. Manning, the forum was greatly modified in its character.
