Learned a little about the Sacred Heart icon (Catholic). It's apparently seen as a symbol of divine love and set in households so that that burning love can be emulated. They say love can keep you on the path to virtue, and prevent one from lapsing into sin.
But often love is used as an argument for universalism, tolerance for bad behavior, acceptance of migrants, welfare, and the like.
Can a Christian make the argument that love begins with one's home and emanates out from that? That just as love motivates you to protect your loved ones from invaders, it might also motivate you to protect your people, country, or heritage? That love, even divine love, might lead you to act in aggression or intolerance of certain people or behaviors?
Or is it pretty much all love thy invader?
