Upon graduating in 1885, Delany joined the faculty at St. Augustine's, where he served until 1908. He taught carpentry and masonry and supervised building projects, as well as (after the ordinations discussed below) serving as the school's vice-principal (1889-1908), chaplain and musician. Although not trained as an architect, Delany is credited as the architect and builder of the Norman Gothic-style
historic chapel, which was crafted in part from stone quarried on campus. Delany and the students also built a library in 1898, and
St. Agnes' Hospital on the College campus. (Completed in 1909, it was the only hospital serving blacks in the area until 1940.) Delany joined Raleigh's St. Ambrose Episcopal Church, where he was ordained a deacon in 1889 and a priest in 1892. Upon being appointed Archdeacon for Negro Work in the
Diocese of North Carolina, Delany resigned his position at the college. He continued to live on campus, as his wife continued to teach and serve as the college's matron. Raleigh's
Shaw University awarded him an honorary degree in 1911 for his educational activities. Delany was unanimously elected suffragan bishop for Negro Work at the North Carolina diocesan convention, and consecrated in 1918. He also agreed to assist the bishops of
East and
Western North Carolina,
South Carolina and
Upper South Carolina in establishing separate black parishes pursuant to the
Jim Crow laws predominant in the south. Bishop Delany advocated keeping African-American Episcopalians united within the Church despite those segregationist practices within the Church and society. ==Death==
