I really don’t think the Sunday pulpit is the place to talk about political parties. There’s already a big disconnect between the pulpit and the pews, and telling people how to vote along party lines won’t do anything.
When it comes to issues, however, sermons should not be crowd-pleasers but speak the Truth. And people need to understand that there are people even in Churches who act like snowflakes and think that their friends’ feelings come before God and just want to be told it’s okay if they do something bad.
There are tactful ways of telling the Truth, but the Church is not nor ever has been a popularity contest.
Those who choose evil need to know their options.
