What is “Mere Catholicity?”
Mere Catholicity is the Christian faith of all people, times, and places. It is an attempt at defining Christianity as broadly as possible, without sacrificing the absolute necessity of a truly Catholic faith and practice. Thus, everyone who considers themselves a “mere catholic” should, in the least, affirm the Holy Scripture as God’s Word containing all things necessary for salvation; the Apostles and Nicene Creed as the summary of the Christian faith; the Seven Ecumenical Councils as the inheritance of dogma; and the necessity of the Episcopate for the fullness and unity of the Church.
