This is quite exciting. A mid-4th commentary on the gospels, mentioned by St Jerome, and others has been re-discovered and published. It is by Fortunatianus, bishop of Aquileia, and is the oldest known Latin commentary on the gospels. St Jerome seems a bit ambiguous about him. In his book On Illustrious Men, he says that Fortunatianus pressurized Pope Liberius in exile to sign the Arianizing creed. But elsewhere he refers to the commentary as a pearl, and also says that he made use of it in writing his own. Anyway, you can read it on-line in English here. The translator’s introduction, and the explanation of how it came to be rediscovered, are available here.

I had a look to see what he might have to say about the great matter of the day. This is what I found:

[Matthew 24:45–51] Who is the faithful and sensible slave whom the master has set over his household? This is understood as a bishop or presbyter giving nourishment to the multitude, for they pass on the commandments. Nourishment at the right time: at what time but this one, which is from the Passion of the Saviour? Nourishment is not only teaching, but is also the sharing of the sacrament. Therefore the one who has faithfully overseen this distribution will receive a reward and be set above all good things in the heavenly kingdom.

But he will eat or drink with the drunkards: what is this but to commune with unworthy people? Drunkards are those who are full of unrighteousness. But in the Church, what is eating other than communion? His lord will come on a day which he does not know: plainly on the day of judgment, or on the day on which he makes him retreat from the world. He will divide him, meaning that he separates the soul from the body. But dividing means to take the soul away from the body, as Daniel said in the story of the two presbyters. He places his share with the hypocrites, meaning that on the day of judgment he will be sent into Gehenna with his companions, where there is continual flame and everlasting punishment. In this torment, it says that there is the gnashing of teeth and weeping of eyes.
