I think the "scholar" you cite needs to go back to the seminary and start over.
From the general website you provided above:
Re. The Resurrection
(Outline below by...) Felix Just, S.J., Ph.D.
B)
Biblical Background of Belief in the Resurrection:
⦁ Earliest Stages in OT: No belief in life after death whatsoever; life simply ceases to exist:
Resurrection in the New Testament
Really? Your Ph.d. scholar really believes that? Evidently he missed some very important teachings and scriptures, to wit:
Psalm 23:6 - "Surely goodness and mercy shall follow me all the days of my life,
and I will dwell in the house of the LORD forever."
Then there's
Daniel 12:2 - "Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt."
And if you want to go back to the Torah, there's this, as explained by Jesus (God), from Matthew 22 (speaking about Exodus 3:6):
That same day the Sadducees, who say there is no resurrection, came to him with a question. "Teacher," they said, "Moses told us that if a man dies without having children, his brother must marry the widow and have children for him. Now there were seven brothers among us. The first one married and died, and since he had no children, he left his wife to his brother. The same thing happened to the second and third brother, right on down to the seventh. Finally, the woman died. Now then, at the resurrection, whose wife will she be of the seven, since all of them were married to her?" Jesus replied, "You are in error because you do not know the Scriptures or the power of God. At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven.
But about the resurrection of the dead—have you not read what God said to you, 'I am the God of Abraham, the God of Isaac, and the God of Jacob'? He is not the God of the dead but of the living."
And there's more examples of his sloppy scholarship in that website but I'll rest with that.
So, your "scholar" has a few fleas. Beware!
