Actually, pedophilia as such has changed over time. It is about the "love" of children.
Technically, I reserve pedophilia for sex with pre-pubescent humans. Once you hit puberty, things bet more complicated, historically, culturally (The Virgin Mary was 14ish when The Holy Spirit "shadowed" over her), and forensically.
Having sex with minors does not a pedophile make.
In fact, in the US we have gotten carried away with labeling folks so-called "sex offenders" for life for the most benign of sexual practices within the context of our legal framework.
Rape a an eight year old and you get out of prison you will registered right a long with the guy who was 25 and having sex with 17 year old.
Insane. The latter shouldn't even be illegal.
Unfortunately, the Vatican tried making this point at the worst of times. The majority of the cases being labeled as acts of pedophilia were often homosexual acts with pubescent boys, sometimes consensually so.
