Sometimes “love of neighbor” takes
the form of concerted action by various cooperating people, which the “neighbor” does not at first recognize as “love”, but hopefully does later on.
On a personal level, this could mean family members doing an intervention on a drug addict. On an international level, Christians came together in the 1940s and imposed certain basic human values on Germany.
Today many Catholics and Protestants are looking for allies in the struggle against abortion and other evils, perpetrated by organized, powerful opponents. It is not “love” to the abortionist when we show passivity.
Prudence, and love, lead us to shift ecumenical priorities away from denominations that are cooperating with evil, and realign with others.
