Thirdly, by copulation with an undue sex, male with male, or female with female, as the Apostle states (Rm. 1:27): and this is called the "vice of sodomy."So, yes, thank you, same-sex sodomy is indeed redundant. Good catch.
As for pederasty, my objection to Cardinal Dulles' omission of sodomy has to be read in the context of the recent scandal concerning clerical sexual abuse, the majority of which occurred with post-, not pre-pubescent minors. So pederasty doesn't quite work for me.
Agreed, though I disagree with your dictionary definition of the word rather than the older definition of the word which is: carnal affections between men and young boys. That's the typical expression that male homosexuality takes on and if the PC press had used that term rather than pedophilia, most people would've had to look it up and the general public would've realized "the bill of goods" that the proponents of "it just a sexual-orientation" continue to try to sell us.
