So now you AND marshmallow disagree on what would be official teaching of your church...
According ot marshmallow, one of you is no longer Catholic...Just thought I'd mention that...
Among the problems that Protestants have is that they do not understand the difference between truth and the expression of truth, between accuracy and precision, and they do not understand the notion of context.
Did you know that if you are baptized with water in the name of the Trinity ou are a member of the Catholic Church? And that, despite the lies of anti-Catholics websites, excommunication does not constitute throwing you out of the Catholic Church?
Precision in discourse requires care and effort. Sometimes I have the energy to show that kind of care and to make that kind of effort. Sometimes not. Here it is Saturday, and my guess is that marshmallow was understandably careless in his or her choice of words.
Make the most of it. I stopped using that sort of gambit in adult discussions back in 1962 when I was 14.
