The SAB says that the Bible has nothing to say about pedophilia. That isn't entirely true. At Deuteronomy 23:17-18 - "There shall be no whore of the daughters of Israel, nor a sodomite of the sons of Israel. Thou shalt not bring the hire of a whore, or the price of a dog, into the house of the LORD thy God for any vow: for even both these are abomination unto the LORD thy God."
On these verses the SAB says: "Don't bring any whore, sodomite, or dog into the house of the Lord. For "these things are an abomination to the Lord." (Sodomites and dogs are biblical names for homosexuals.)"
Actually, the KJV uses Sodomite in the place of catamite, which is a boy kept for the purpose of sexual perversion. The dog was typically used by Israelites as a figurative representation of morally unclean persons and often applied to sexual perversions in this way, for example the term dog in verse 18 of Deuteronomy 23 is applied to a pederast; one who practices anal intercourse, especially with a boy. (A Greek-English Lexicon, by H. Liddell and R. Scott, Oxford, 1968 p. 1450)
Where the Bible condemns pederasty and young boys used as temple prostitutes the SAB has mistakenly considered it a comment on homosexuality.
There are a couple reasons why pedophilia isn't often specifically mentioned in the Bible. First of all, because homosexuality, adultry, and premarital sex were all against the law, which would make most cases of pedophilia against the law. The custom was to wait until maturity, and although there was no specific law against marriage of a certain age, a law against pedophilia would have been unnecessary. The Bible doesn't mention pedophilia specifically because it didn't need to.
Secondly, it was not uncommon for a young maiden, such as Mary for example, at the age of 15 or 16, to be married to a much older man, like Joseph for example, at the age of about 32. By modern day American standards that would be classified as pedophilia.
