[8] The slow release of the Vatican's report on McCarrick was "evil", said Strickland in an October 2020 interview, while inviting Pope Francis to "go ahead and fire me" for this comment.

In an open letter to the faithful of the Diocese of Tyler in October 2023, Strickland refused to resign, "because that would be me abandoning the flock that I was given charge of by Pope Benedict XVI".

[17][18][19] In an online interview given several hours after his dismissal, Strickland stated that he was uncertain of the exact reason he was removed from office, "except I've threatened some of the powers that be with the truth of the Gospel".

[34] On 31 October 2023, Strickland attended a meeting in Rome hosted by the Catholic website LifeSiteNews: during it, he read a letter from an unnamed friend, in which the Pope was described as "an expert at producing cowards", "one who has pushed aside the true Pope and has attempted to sit on a chair that is not his", a "usurper of Peter’s Chair" and a person who "proclaims the devil’s voice to be the voice of the Holy Spirit"; the letter also quoted Revelation 17:11, a part of the Bible that is generally interpreted as a reference to the Antichrist.
