The Domestic Missionary Society of the Episcopal Church in New York sent a clergyman, hymnals and prayer books.

By the turn of the Twentieth Century the congregation had outgrown its church building and the present structure was completed in 1903.

Cathedrals in the Episcopal Church in the United States were not popular until the Oxford Movement began.

Bishop Thompson moved to Jackson and believed the cathedral should be in the city where he resided.

Therefore, St. Columba's Church was named the diocesan cathedral and served that purpose until just after Thompson's death.

St. Andrew's, which grew to become the largest parish in the diocese, was elevated to be the cathedral on January 19, 1966.

When it was built the roof featured a gable in the middle of each side with elaborate trim, which was typical of the late Victorian period.
