In the Diverge Content pack there is a list of props that you can use for your role play within the city. There is a section that has a cross. But for some reason the cross is not able to be spawned. I don't see a reason why it shouldn't be able to be used during role play. I think it should be added in the game for the priest's and people who love Christ in game. By the way I was going to post this on December 25th the day that Christ was born, but I was a bit busy with hanging out with family.

May Christ Be with you all.
