I don't see any offence in anything that you said at all and fully agree that everyone has the right to say what they like as long as they speak not with the direct intention of causing hurt to another. Although I am not RC I do not believe that doctrines on their own hurt anyone. Only the interpretation and perhaps misguided actions claimed to be in association to those doctrines cause harm.
It is ok to share a faith if done in a loving manner. When my former boss and now close personal friend, had a nervous breakdown, I was able to overcome the cultural tendency to 'give him space' and instead share my relationship with God as a way to help me get through things, with him. Although he was an unbeliever, he really appreciated my communication with him and wanted to know more about the god I believe in, that caused me to be the person he believes I am. He has a number of philosophies and we regularly discuss them. I have a number of very close devout Muslim friends. We always focus on similarities and invariably discover that we have far more in common than it would initially appear. We only argue about football; he supports Liverpool and I Arsenal.
Certainly religion as a national policy would not work and is inappropriate as a personal relationship with God is required and God's word also speaks of free will.
I can be described as a Charismatic Pentecostal and Pia is a Catholic. She understands why I don't 'believe' in certain rituals and traditions as mine is a purely bible-based faith. I similarly, attend mass regularly in da Phils and focus on similarities rather than differences. The most important thing is that we believe in the same God, pray together and are tolerant of each other's perspective because we love each other.
As we study the word more together we will find our own unique faith positioning as a couple.
