Mortalium Animos, an infallible teaching of the Church, forbids Catholics from participating in any non-Catholic assembly.

[annalex]

Mortalium Animos has for its topic ecumenical efforts leading to indifferentism. Surely it does not forbid, for example, secular assemblies where Catholics mix with non-Catholics. None of that is happening when a Catholic cleric is present, not joining in any service or prayers.

Again, I don't like it because I don't see how it helps in conversion of the Jews, but I defer to the Roman Pontiff to decide for himself. It is certainly a salutary development that Catholic-Jewish relations warmed up a bit.

That is my last post on this topic on this thread. You can rant on without me.

Infallible...is that one of those ex-cathedra declarations?

If so, a Catholic is forbidden to attend a protestant church service?

Is a Catholic representative forbidden to attend the daily prayer in the House of Representatives?
