Find common ground and stick to that.
Enjoy your work, serve the Lord and teach her by example of your excellence, patients, and kindness.
You are the elder and should be honored, but do not expect it. And you should respect her for her abilities and give no heed whatsoever to her politics. Help her to become a good leader, and she will come to understand your values.
“You are the elder and should be honored”
That used to be the case between us but, apparently, no longer.
