Dear Christians of Reddit, I need help.

Hi! I need help. My friends mom found out she was gay and my friends mom is…to put it nicely, not taking it well. My friend gets all her texts read and we’re minors so we can’t do much about it. I want to be there for her and invite her over to my house as much as possible, but her mom…it’s not my story to share more than I need to. Long story short her mom’s really strict, even more so after finding out she’s gay. Because of this I’m going to act as Christian as I can, even going to go buy the Bible later to pull the act together. This is getting kind of lengthy so I’ll get to the point. Could you guys please let me know how a Christian might act or think about certain topics? What might be brought up in conversation? Please help, and bless all 🙏
