I just made an important edit to the article, from the book of Hebrews:
BF (Brian Flemming of “The God Who Wasn’t There” DVD): (shows on screen Hebrews 8:4, translated as) “If Jesus had been on earth, he would not even have been a priest.” (Hebrews 8:4)
The meaning is that Jesus is in heaven now as our ‘great High Priest’, he is not on earth now, etc. Literally: 'if He were on earth…" * “…he would not be a priest, for there are already priests [on earth] who offer the gifts…” (Heb 8:4). This implies Jesus was on earth before, but he is not now on earth. It does not mean Jesus never lived on earth or he never was on earth (See the context Hebrews 8:1-6, and other clear passages from Hebrews, etc)
“Now the main point of what we are saying is this: We do have such a high priest, who sat down at the right hand of the throne of the Majesty in heaven, and who serves in the sanctuary, the true tabernacle set up by the Lord, not by a mere human being. Every high priest is appointed to offer both gifts and sacrifices, and so it was necessary for this one also to have something to offer. If he were on earth, he would not be a priest, for there are already priests who offer the gifts prescribed by the law. They serve at a sanctuary that is a copy and shadow of what is in heaven. This is why Moses was warned when he was about to build the tabernacle: ‘See to it that you make everything according to the pattern shown you on the mountain.’ But in fact the ministry Jesus has received is as superior to theirs as the covenant of which he is mediator is superior to the old one, since the new covenant is established on better promises.” (Heb 8:1-6, NIV)
“Since the children have flesh and blood, he too shared in their humanity [or ‘took part in the same’] so that by his death he might break the power of him who holds the power of death – that is, the devil – and free those who all their lives were held in slavery by their fear of death. For surely it is not angels he helps, but Abraham’s descendants. For this reason he had to be made like them, fully human in every way [or ‘made like His brethren in all things’], in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people. Because he himself suffered when he was tempted, he is able to help those who are being tempted.” (Heb 2:14-18 NIV)
“During the days of Jesus’ life on earth [or literally ‘in the days of His flesh’], he offered up prayers and petitions with fervent cries and tears to the one who could save him from death, and he was heard because of his reverent submission. Son though he was, he learned obedience from what he suffered and, once made perfect, he became the source of eternal salvation for all who obey him and was designated by God to be high priest in the order of Melchizedek.” (Heb 5:7-10 NIV)
The more literal NASB of Hebrews 8:4 has “Now if He were on earth, He would not be a priest at all, since there are those who offer the gifts according to the Law…” The teaching of Hebrews is Jesus is our great High Priest in heaven and that is only possible because of his one-time sacrifice of his body on earth (Heb 10:5,10, 14; 2:14-18; 5:7-10; cf. 1 Pet 2:24; 1 John 2:1-2; etc).
The old Jewish sacrificial system (which was a copy and shadow) is done away with and fulfilled in the one sacrifice of Christ on the cross. “Therefore, when He comes into the world, He says, ‘Sacrifice and offering You have not desired, but a body You have prepared for Me…’ …By this will we have been sanctified through the offering of the body of Jesus Christ once for all.” (Heb 10:5,10 NASB).
In Catholic theology, this single sacrifice is renewed or re-presented (made present) every time the priest says Mass and offers Eucharist, which is the body and blood of Christ (1 Cor 10:16ff; 11:23ff; Matt 26:26ff; Luke 22:19ff). Hebrews is quite clear that Jesus Christ like us had flesh and blood, shared in our humanity, was made fully human in every way, lived on earth ‘in the flesh’, etc.
