"Why I Am Not SSPX" by James Larson
James Larson's "Why I Am Not SSPX
" makes some good points, especially by quoting Pastor Æternus
Hence we teach and declare that by the appointment of our Lord the Roman Church possesses a sovereignty of ordinary power over all other Churches, and that this power of jurisdiction of the Roman pontiff, which is truly episcopal, is immediate; to which all, of whatsoever rite and dignity, are bound, by their duty of hierarchical subordination and true obedience, to submit, not only in matters which belong to faith and morals, but also in those that appertain to the discipline and government of the Church throughout the world; so that the Church of Christ may be one flock under one supreme pastor, through the preservation of unity, both of communion and of profession of the same faith, with the Roman pontiff. This is the teaching of Catholic truth, from which no one can deviate without loss of faith and salvation.
