> stating that one cannot receive salvation except through the Catholic Church

The contemporary position of the Catholic Church is that non-Catholic Christians and non-Christians can be saved. What you've said there will be read by many readers as saying that only Catholics will be saved, which is not the Catholic position at all, in fact it is the condemned heresy of Feeneyism.

Now, the Catholic Church also teaches that when non-Catholics and non-Christians are saved, they are saved through the Catholic Church – but in a mystical rather than visible way – so what you've said is literally true, but is prone to misinterpretation.
