The High Priest
Jesus, with his death in the cross, tore the veil that separated the people, of the Saint of saints, and turned into the High Priest for ever (according to the order of Melchizedek), and ended with the Levite priesthood of the Jews, as confirmed in almost all the book of Hebrew. Jesus, before rising to heaven, in the 3th encounter with his (7) disciples, confirmed the key to heaven and said three times to Peter: John: 21. 15 a 17.
15- So when they had dined, Jesus saith to Simon Peter, Simon, [son] of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs. (Lamb, who, in absence of the shepherd, cares repairs and feeds the heard).
The 1st times were for Peter lead and repair the other pastors and deacons, like

presbyter (Bishop), as the high priest was superior of the priests and Levites.
Now the 2nd timewas for Peter and all lambs of the time of the 1st shack - Jesus said: do you love me?
Graze my sheep. (Note: To graze is to give pasture, and only Jesus feeds us with his word; now to care is to take care for your Lord).
In that 2nd time, was for Peter and the others to gaze, since the word (his gospel) still wasn´t written. And Jesus, speaking for the 3th time to Peter (Like the 70 disciples, who are all in all times): Luke. 10:
3- Go your ways: behold, I send you forth as lambs among wolves. (your lambs in all times have to be taken care of, only for love, and makes very clear who owns the sheep).
Jesus asks for the 3rd time to Peter (to us): do you love me? Jesus told him:
Take care of my sheep.
