[Polycarp]

The authenticity of this letter can only be believed if there is a link between sexual depravity and profound stupidity.

Well, to paraphrase St. Aquinas:

"Sin makes you stupid."

[ninenot]

I believe that TA was referring directly to sexual sins when declaring that such "darkens the intellect."

It certainly would explain the fact that a whole lotta Catholics of my acquaintance, ordained and not, can't construct an intellectually-compelling argument for the abuse of the Liturgy and other foofoodust they spread around.

In fact, their arguments generally read like your "letter" to Adamec.
