November 12, 1919, the X Club would select Theta Kappa Phi as its new name. At the time of its adoption, the letters simply stood in place for ‘The Catholic Fraternity’ before they were given a secret meaning later on upon merger into Phi Kappa Theta in 1959. The founding group would elect Concilio as the fraternity's first president. Under him, he successfully began the infant fraternity's nationalization by unifying with the local fraternity of Kappa Theta at Pennsylvania State University, establishing the group there as its Beta chapter on March 22, 1922. Meanwhile, the fraternity would receive valuable help and inspiring leadership from local Bethlehem pastor, Rev. William I. McGarvey. Since none of the existing members had fraternity experience, McGarvey was a valuable asset in developing the fledgling group into a true fraternity in its early days. McGarvey would additionally secure the help of Rev. Michael Andrew Chapman in writing Theta Kappa Phi's ritual, who was an Episcopal priest as well as a member of Sigma Alpha Epsilon at Bard College. The basics of Theta Kappa Phi's ritual are still used in Phi Kappa Theta's ritual today, while McGarvey's effort for Theta Kappa Phi have seen him recognized as the fraternity's fourth founder, alongside Concilio, Carr, and Bobbin. Theta Kappa Phi would continue to expand to other colleges and universities in the surrounding region. By the time the merger came about in 1959, Theta Kappa Phi maintained 24 open and active chapters across the United States. Merger into Phi Kappa Theta Phi Kappa and Theta Kappa Phi were both founded upon Catholic principles. As such, the two fraternities had extensive interactions in the years that lead up to their eventual merger. Four chapters from each would share the same host institution (University of Illinois, Pennsylvania State University, Ohio State University, and University of Missouri) by 1959. In 1921, only two years after Theta Kappa Phi's founding, Phi Kappa proposed a merger with them. However, Theta Kappa Phi declined and merged instead with Kappa Theta, a local fraternity at Penn State, in 1922. Over fifteen years would pass until talks of a potential merger began again in 1938. A joint committee, sanctioned by both fraternities and attended by representatives from both groups, was created to discuss this possibility. Discussion and negotiations pertaining to the merger would continue over the next two decades. By 1957, both Phi Kappa and Theta Kappa
