Yes we agree but He cannot be high priest without low priest?
The apostles / bishops and those who they ordain are low priests of the same order of melchisedec offering the same sacrifice
No man can ordain anyone or sanctify anyone as it all comes by God in who He calls to His ministry here on earth.
It's sad when only Catholics think they have all truths and that the Roman Catholic Church is the only the true church and everyone else are heretics. This is the spirit of antichrist who blinds the eyes of those who think they are wise, but are found to be foolish and prideful as they would rather follow a man's doctrine and practice the earthly rituals and traditions and ignore the doctrines of Christ. There are many Catholics that go to mass, but still do not agree with all the doctrines and rituals of the Catholic church.
Here is what scripture says about a royal priesthood as all who are of Christ own are a royal priesthood.
1Peter 2:9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
1Peter 2:10 Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.
Here is God's order in His true church as I only used this part of the verse as the rest come after the first order.
1Cor 12:28 And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers
The office of bishops and elders are taught in the Bible, but I see nowhere where it mentions the word Pope or that he is to be called "Holy Father" in fact scripture says to call no man father.
Mat 23:8 But be not ye called Rabbi: for one is your Master, even Christ; and all ye are brethren.
Mat 23:9 And call no man your father upon the earth: for one is your Father, which is in heaven.
Mat 23:10 Neither be ye called masters: for one is your Master, even Christ.
Mat 23:11
But he that is greatest among you shall be your servant.
Mat 23:12 And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted.
