good. this has been abused for too long. I know plenty of “pastors” who claim to be “pastors” so they can deduct their entire mortgage. I bet you do too. Jessie Jackson for one.
The abuses you mention are not common. I know that in my Lutheran Church-Missouri Synod, the vast, vast majority of my fellow pastors are NOT getting rich, and they are NOT abusing the housing allowance. Most of us are way underpaid, relative to our education, and overall the salaries and benefits are getting worse.
