Laudator Temporis Acti

Peter Levi, The Hill of Kronos (New York: E.P. Dutton, 1981), p.10:

But I came late to Greece, at the age of thirty-two, in 1963. I had started to learn ancient Greek as a schoolboy, at a school where Greek was hardly taught. All I knew about Greece then was the Elgin Marbles, of which I treasured some sepia-tinted and forbidding postcards, and the fact that Oscar Wilde, who in the summer of my fourteenth birthday had just become my literary idol, said the Greek text of the Gospels was the most beautiful book in the world. So I demanded to learn Greek, and changed schools in consequence. From that time I have never ceased to study the Greek language.

Did Wilde really say that, and, if so, where?

Update: Thanks to Dennis, who cites the following from Oscar Wilde, De Profundis:

At Christmas I managed to get hold of a Greek Testament, and every morning, after I had cleaned my cell and polished my tins, I read a little of the Gospels, a dozen verses taken by chance anywhere. It is a delightful way of opening the day. Every one, even in a turbulent, ill-disciplined life, should do the same. Endless repetition, in and out of season, has spoiled for us the freshness, the naivete, the simple romantic charm of the Gospels. We hear them read far too often and far too badly, and all repetition is anti-spiritual. When one returns to the Greek, it is like going into a garden of lilies out of some narrow and dark house.
