My mother and teachers used the term “Church Militant” when I was growing up, before the world ever heard of Trump. It was understood that doing things such as praying the rosary, standing up for what’s right, joining the Legion of Mary or the Blue Army, etc was being part of the Church Militant. This is also why a lot of prayer-oriented groups have military-sounding names.
I believe it was also discussed in our Baltimore Catechism though it’s been a long time and maybe I’m confusing it with some other textbook. As discussed in Wiki, it’s a basic Christian theology concept that there is a Church Militant, a Church Penitent, and a Church Triumphant.
Jamie, it’s not anything to “lol” at and to do so is disrespectful. A basic theological term being co-opted for political hooha is also disrespectful in my mind, though, and I doubt that anyone involved in writing such gunk for the NY Times has any idea about the underlying concept or a clue about it beyond wanting to write another anti-Trump article.
I am in one prayer group that characterizes itself as “church militant”, which among other things has prayed against abortion and has prayed that God will protect our country and president and guide him and our leaders. To me, this is stuff you should be praying for every day regardless of who is sitting in office.
