He studied at the Virginia State College, from were he graduated with a Bachelor of Arts in 1952.^[2] He then studied at the New York University and graduated with a Master of Arts in North American history and constitutional law in 1953.

Gunn of Southern Virginia.^[4] He then became curate at St Philip's Church in Brooklyn, New York City, and in September of that year became curate at the Cathedral of St. John the Divine.^[5] During his time at the cathedral, he was ordained priest in June 1958 by Bishop Horace W. B. Donegan of New York. In 1960 he became vicar of St Cyprian's Church in Hampton, Virginia, and between 1961 and 1965, he also served as assistant professor of history and constitutional law at the Hampton Institute. In 1965, he returned to New York City and became residentiary canon of the cathedral chapter of the Cathedral of St. John the Divine. During that time he became well known for his involvement in social issues and civil rights. He also taught Christian Ethics at the General Theological Seminary.^[6]

Dennis was elected on the third ballot as Suffragan Bishop of New York, during a special convention of the Diocese of New York in 1979.^[7] He was consecrated at the Cathedral of St. John the Divine on October 6, 1979, by Bishop Paul Moore Jr. of New York. Dennis was favored by many to be elected as diocesan bishop during the 1989 election, however he withdrew the nomination citing medical reasons. He retained the post till his retirement in 1998. He died on March 30, 2003, in Hampton, Virginia.^[8][9]

He drafted the "Dennis Canon" which seeks to impose a trust, in favor of the Episcopal Church, on property held by a local group of Episcopal adherents. Its intended effect is to discourage a local group from withdrawing from the Episcopal Church, as under the Dennis Canon such property would revert to the Episcopal Church.
