We should stop trying to evangelize Protestants, some Catholics say. “Let’s get our own house clean first, before we invite our fellow Christians in,” someone commented on a recent article of mine that presented a Catholic rejoinder to a prominent Baptist theologian. Another reader argued that, rather than trying to persuade Protestants to become Catholic, we should “help each other spread God’s love in this world that seems to be falling to pieces before our eyes.” As a convert from Protestantism, actively engaged in ecumenical dialogue, I’ve heard this kind of thinking quite frequently. And it’s dead wrong.
