Thomas P. Halton, a retired professor of Greek and Latin at Catholic University who wrote several books on early Christianity, died May 29 at Sibley Memorial Hospital in the District. He was 88.

The cause was complications from pneumonia, said his partner, Stella O’Leary.

Dr. Halton, a Chevy Chase resident, taught at Catholic University from the early 1960s until retiring in 2000.

From 1987 to 2009, he was the editorial director for the university’s “Fathers of the Church” series, which translated early Greek and Latin church literature into English. He was a past president of the North American Patristics Society, an organization of church scholars.

Dr. Halton’s work on early Christianity was widely published, and his latest book, “Theodoret of Cyrus: A Cure of Pagan Maladies,” will be printed in June.

Thomas Patrick Halton was born in Kilnaleck, Ireland. He was a 1946 graduate of St. Patrick’s College in Maynooth, Ireland, and was ordained at the college in 1950, O’Leary said. He received a master’s degree in ancient classics from University College Dublin before immigrating in about 1960 to Washington, where he received a doctorate from Catholic University.

Survivors include his partner of 36 years, Stella O’Leary of Chevy Chase.
