Alan Jacobs warns converts who would be apologists:
Waugh is one of those converts in whom Catholics take great pride. If I were in their position, I would do everything in my power to prevent the world from finding out that he belonged to my communion. If the rightly administered sacraments are presumed to be instruments of grace, it appears that Waugh, at any rate, was invulnerable to their power. I would appreciate it if my Catholic brothers and sisters took the unremitting nastiness of the man more seriously. I have yet to hear one say that when Waugh took the Sacrament he did so unworthily, though I do not believe, given his gleeful and freely expressed hatred of almost everyone he knew, that anyone could reasonably say that he did so worthily.
He believed that by becoming Catholic he had ensured his own salvation, and from that elevated seat taunted his friends who remained Outside: “Awful about your obduracy in schism and heresy,” he wrote to the Anglican John Betjeman. “Hell hell hell. Eternal damnation.” Only some wholly unacquainted with Waugh’s views would think he was joking. Betjeman certainly didn’t.
