Haydock isn’t lashing out. And he was definitely not high and mighty! George L. Haydock was a member of an English Catholic family that suffered under persecution; he even had martyrs in his family. He became a Catholic priest at a time when it was very difficult to be a priest in England, and he served country Catholics in rural places.
Haydock completed his Commentary as a newbie priest at his first assignment, Ugthorpe, where he also had to build a chapel and all the parish buildings. His commentary met a crying need for something Catholic, recent, and in English. (It also included a lot of apologetics points, as you just found out.) But if you really want a full commentary that talks about everything at length, Haydock would be the first to tell you that he isn’t it. (He would probably have gone to Fr. Cornelius a Lapide’s Great Commentary, if he had a copy and could afford the giant tomes.)
Wikipedia currently has
a nice article about Haydock and his commentary. Some parts are an illustrated version of the Catholic Encyclopedia entry, but that’s not a bad thing! However, there is also a lot of new info or hard-to-get info. Somebody put a lot of work into it.
As for what the Timothy comment says, it’s not radical. I’m an educated person, but I had to learn a lot about the Bible before I could really understand it. I still misunderstand it in places, so it’s good that I have the Church to teach me. As the Ethiopian eunuch who was reading Isaiah, said to St. Philip, “How can I understand unless someone teaches me?”
So of course I don’t have the power to define what the Bible says, or to tell other people to follow my interpretation. Anything I say that contradicts the Church over the ages, you should just ignore.
UPDATE: Actually, Haydock did the Old Testament, but couldn’t work fast enough to do the New Testament. So a bunch of guys under Fr. Benedict Rayment did the New Testament part; it’s just called the Haydock Commentary because they released it as a single project, together. (And the publisher was Thomas Haydock, Fr. George’s brother.)
So any objection to the phrasing of the Timothy commentary should be directed to Fr. Rayment!
