While the traditional social fraternity is a well-established mainstay across the United States at institutions of higher learning, alternatives - in the form of social fraternities that require doctrinal and behavioral conformity to the Christian faith - developed in the early 20th century. They continue to grow in size and popularity.

Christian fraternities were established in the early part of the 20th century; the three largest were Beta Sigma Psi, Alpha Gamma Omega, and Sigma Theta Epsilon, which are still active.

Beta Sigma Psi, the oldest Christian fraternity, was founded as a national fraternity for Lutheran students in 1925 at the University of Illinois, home to the largest Greek System in the United States. The fraternity had its origins in the concerns of Rev. Frederick William Gustav Stiegemeyer, the son of a Lutheran pastor, who had been entrusted with the spiritual care of Lutheran students at the University. In the fall of 1919, he organized the Lutheran Illini League with a nucleus of ten students. At that time their intention was to meet once or twice a week for religious instruction and discussion on contemporary issues. In the fall of 1920, now with twenty members, the Lutheran Illini League rented a house, and in early 1921 reorganized as the Concordia Club. By 1923 the group regularly participated in campus activities; so much so that they began being referred to as the "Concordia Fraternity." On April 17, 1925, incorporation papers were filed for Beta Sigma Psi National Lutheran Fraternity in Springfield, Illinois. By 1970, Beta Sigma Psi had grown to eighteen chapters. The fraternity had ten active chapters as of 2016.

Alpha Gamma Omega was established in 1927 at UCLA. The fraternity suffered a decline in chapters and membership before experiencing extensive national growth starting in 1987. As of 2016 it had twelve active chapters.
