„Conventional wisdom tells us to avoid (at all costs!) familial discussions about religion and politics. Yet our faith may in fact lead us directly into disagreement with relatives and other close members of our community. It shouldn’t surprise us; Jesus himself spoke about disciples leaving everything to follow him—including their own families (Mark 10:29–30). Unlike those early disciples, many of us often resist allowing that level of discomfort to creep into our relationships.
This resistance is understandable, of course, for Scripture also consistently speaks to the importance of maintaining healthy relationships. In Matthew 15:4, for example, Jesus reiterates the Old Testament command for children to honor their parents. Psalms and Proverbs are replete with familial instruction; the Epistles echo much of this as well. I’m not suggesting that we simply get on our proverbial soapboxes and speak our minds, regardless of the relational cost.”
