Wise clergy will leave well enough alone. Must congregations forget the ideas from the sermon or homily five minutes after the preacher has finished speaking. If clergy lace their sermons with political "support of or arguments against" a given politician the congregants will remember only that the clergy spoke against their chosen politician. Those who agree will not react since they are the "choir" to whom the preaching is directed. Those who will feel spoken against will drop their contributions either in full or in part since they will no longer feel like welcome members of that congregation. If Johnson is rescinded there will also be pressure from the 'right-wing' to force clergy, particularly priests, to preach for the GOP. If they do not preach as 'directed' they will be called out to their bishops. I can't imagine any priest wants to either divide his congregation or be called out by influential (big wallet) parishioners.
