Pure, unadulterated, TRADITIONAL (as in, how the Church was in 1958, not the new stuff) Catholicism. Rather, where “sin is sin”, and one must repent and do pennance and believe the gospel, even as Jesus imparted it:
Namely, Catholics who reject all popes involved in the post 1958 era of “Vatican II”, and attend only the Latin mass in faithfulness to the constant teaching of the church, known as Sedevacantists, we who acknowledge that since faithful Pope Pius XII (1958) we haven’t had a valid pope.(A Sedevacantist is one who believes the chair of Peter is currently vacant.)
