One of the reasons
I was so disappointed in the 2008 X-Files movie (which had obvious anti-Catholic themes) was because the TV show itself had often portrayed Catholicism (or Catholic themes) favorably. I’m watching the entire series again from start to finish. I am just into season 3 right now. I’m starting this thread to catalog some of the “Catholic” moments in the series. Episode titles follow with a brief description. This thread may contain SPOILERS, meaning some of the descriptions may give away parts of the show, but I will try to avoid giving away anything significant.
Conduit - Mulder, in anguish over his sister, prays in what looks to me like a Catholic church. Here’s a screenshot of that one:

**Miracle Man ** - Scully reveals she was raised Catholic and that she knows in Scripture the devil never steals the show.
Sleepless - The character “Preacher” crosses himself before killing a doctor, although he is depicted as a self-authoritative interpreter of the Bible throughout the rest of the episode.
3 - Referring to the message of John 52:54 written on the wall of crime scene by vampire killers, Mulder says, “they have the same feeble literal grasp of the Bible as all those big-haired preachers do.”
Die Hand Die Verletzt - Girl escaping the satanic ritual runs away in fear, praying the Hail Mary. She successfully escapes. (smart girl

)
Colony - Mulder receives emails of obituaries of 3 abortion doctors suspected of being killed in arson fires by “militant right-to-lifers” who are later absolved.
Fearful Symmetry - A night janitor crosses himself in the teaser scene when an invisible force destroys the surroundings, and a trucker moments later yells “Mother of God” when he sees an elephant about to hit his truck.
Dod Kalm - The captain, after sending his deceased first mate to sea, crosses himself. He later turns out to be not so good of a character.
The Calusari - Scully believes the miracle of the loaves and fishes is “a parable.” The hint in the episode is she’s wrong, however. Later they perform what resembles an exorcism, but it is some other kind of ritual done by Romanian men that do not appear to exhibit Christianity in the ritual.
Soft Light - Scully is shown paying respects at what appears to be the very end of an outdoor Catholic burial for Agent Ryan. A collared priest presided.
Our Town - Mulder tells Scully to consider that cannibalism could prolong human life by citing historical beliefs such as “from vampirism to Catholicism, the reward for eating human flesh is eternal life.” [paraphrasing]
If you know of a scene I missed or want to share comments, all are welcome. This thread to be continued as I watch more…
