Are There Contradictions in the Roman Catholic Church? Robert Sungenis Responds to Steve Christie

Robert Sungenis issued a challenge to Protestant Steve Christie to provide one example where the Catholic Church has contradicted itself in official matters of faith and morals that have become infallible. Robert told Steve in their recent debate on Marian dogmas [May 5, 2023] that if Steve could find one legitimate contradiction, Robert would become a Protestant. Steve submitted his list of “contradictions” to Robert on May 11, 2023. Suffice it to say, there were no contradictions in Catholic doctrine, just misunderstandings, and statements that needed more clarification. DOWNLOAD PDF

Robert Sungenis' Review of: Extraterrestrial Intelligence and the Catholic Church: Are We Alone in the Universe with God and the Angels? Authored by Paul Thigpen

After a lifelong contemplation of the subject, popular author Paul Thigpen has decided to make a case for aliens living on other worlds, and perhaps visiting ours. Catholics will be interested in what he has to say because Paul attempts to use scriptural, magisterial, and traditional sources to support his pro-alien view. The book is 433 pages, half of which is an historical overview of the subject from Plato to Pope John Paul II.  The research it must have taken to collect and collate everyone who ever had a published thought about aliens is remarkable.

Catholic Answers’ Heterodox Position on Biblical Inerrancy  Written by Robert Sungenis  October 4, 2022  Source: The following is a fictional dialogue crafted by Michael Lofton who is employed by Catholic Answers. It is critiqued by Robert Sungenis, director of Catholic Apologetics International Elijah: I’ve been looking into the Catholic perspective, and I came across this massive debate on whether or not the Second Vatican Council affirmed or denied inerrancy.  Seraphim: I can imagine. This is a really complex issue. Let’s start by defining our terms. What do you mean by inerrancy?  Elijah: Well, that is just the thing! I’m not sure I have a proper definition. However, for the moment, let’s use this as a working definition: inerrancy means there are no errors in the Bible.  Seraphim: We will certainly need to tweak that definition.  Elijah: How come? Did Vatican II teach something different?  Se
