Um, the only feelings I trust is about reading anything by Neil Donald Walsh. This is new age kind of stuff, definitely not catholic. Plus, I remember in my new age days being in a workshop with this guy long before he was known for these so-called conversations with God. I hope this isn’t a Catholic church group that is discussing his books.
However, I will answer the original question. I don’t believe we can always trust our feelings because they are influenced by too much else - whether we had enough sleep, whether we just had a fight with someone, etc. Besides, how does Walsh know how God communicates to someone? God is unlimited and can communicate in any format and it seems in the past that God spoke in words to Moses and to others.
