Well, that IS the orthodox system of belief. Along with the idea of trinity. There is no law of sacrifice. And you need to reread Hebrews if you cannot see the priests involvement.
Just some of the verses in Hebrews:
For every high priest taken from among men is ordained for men in things pertaining to God, that he may offer both gifts and sacrifices for sins:
And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham:
For the priesthood being changed, there is made of necessity a change also of the law.
Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.
For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.
For if he were on earth, he should not be a priest, seeing that there are priests that offer gifts according to the law:
And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins:
And having an high priest over the house of God;
For the bodies of those beasts, whose blood is brought into the sanctuary by the high priest for sin, are burned without the camp.
Christ isn't a priest. Nor should high priests compare themselves to him. Every Gospel and Pauls letters have the enemy of their teachings as the "high priest(s)". The veil was a door for high priests. Jesus destroyed it, and priests were no longer needed.
Priests concocted the Bible books. Surely, Hebrews was written by a priest or for the priests.
Hebrews has no gospel message that I would follow, though it may "appear" to sound right.
