There is an unwritten rule in Christian culture that pastor’s wives do not work outside the home. Once married, most pastor’s wives relinquish their vocation and set about the full-time business of wifedom. They are very earnest in their mission to be their husband’s support, encourager, and Proverbs 31 vixen.
Most pastor’s wives are indeed college educated (though often partially), having secured their husband by way of their university’s Campus Crusade ministry. The rest of them met at Christian college where most everyone is looking to mate for life. If said wife does work outside the home after they are married, she will without question quit her job when they start having children. (And they will have more than one. You won’t find a pastoral couple who has only one child. It does not exist in nature.)
The pastor’s wife keeps extremely busy with her homeschool curriculum, coordinating the children’s ministry at church and leading Beth Moore bible studies. But once the kids are grown and out of the house it is common for the pastor’s wife to get her real estate license. This is an excellent business move, for from here she automatically becomes the real estate agent for every single person in the congregation.
