There was a small discussion today at my work about in vitro, and I just sat by, continuing to do what I was doing, without saying a word. I know I should have proclaimed the Truth of what the Church teaches, but I didn’t. Is this mortally sinful?
Now, these people were not attacking the Church in any way, but they were just talking about in vitro like it was OK.
At the very least, I feel like it was a missed opportunity to witness to the Truth, and at the worst, I feel like it could have been a mortal sin.
