Today my sister did a religious marriage, i.e., she was already married legally but redid the religious ceremony.
The group is called the "Pius Brόder", which is essentially a comparatively extremist wing the of Catholic faith associated with all sorts of conspiracy thinking. The sermon was partially in Latin and they have to kneel all the time, and they e.g. did the thing where you eat a small cracker and think it's Jesus' body.
The Priest's speech was pretty interesting, saying that e.g. women have never been objectified as much as today, while also saying that they should be mothers and not work. But what stuck out to me the most was that the sermon seemed quite cold. My impression from watching more milktoast sermons is that the people are genuinely compassionate and care more about people being nice than faithful. But this felt like the main point was actually to believe so that you go to heaven rather than hell.
