Catholics claim that when Jesus Christ established his Church, he permanently endowed her with a Magisterium that can teach infallibly on matters of faith and morals.

The following is a guest post written by Devin Rose.  Devin is a 32-year-old software engineer and lay apologist who blogs at St. Joseph’s Vanguard.

Recently I was asked for my evaluation of Doug Wilson’s article titled “Authority and Apostolic Succession.” For the sake of any others who may be interested in a Catholic evaluation of Doug’s article, I am posting my evaluation here.

Throughout the past year on Called to Communion, the various blog posts and full-length articles by the contributors have been met with objections of various stripes and sizes.
