In a recent BBC interview, Anthony Fauci reflects on his own “complicated” relationship with the Catholic Church. Fauci is divisive as a public health figure—and his merits in this area are not my concern here—but many, indeed most, baptized Catholics would find this to be a respectable take on religion. From a spiritual vantage point, this lukewarm Catholicism is not only incoherent but also gravely dangerous. So, because you are lukewarm, and neither cold nor hot, I am about to spit you out of my mouth. If Oecumenius is right, then being a lukewarm Catholic is even worse than being outside of the Church entirely.
