At this point, Rogar would like to give the phylactery of faith to Ansiris.
"I've got all the assurance I need from Torag for now, and it seems like you keep bringing up morality. If you don't like the idea of something, just ask Iomedae."
If Ansiris doesn't take it, he will toss it to him, and walk off. He feels that this is likely both the easiest and the most effective solution to the point that he'll be surprised if it comes up again.
In case this gets misinterpreted, this is not a jab. This is Rogar taking the best course of action he can come up with.
