I will feed my sheep: and I will cause them to lie down, saith the Lord God.
Then, later on in the same chapter, God says, ...
AND I WILL SET UP ONE SHEPHERD OVER THEM, and he shall feed them, even my servant David: he shall feed them, and he shall be their shepherd.
"Could one be a practicing and faithful Jew if one repudiated the authority established by God? (David and his sucessors)
In the New Testament, Jesus repeats the same pattern...
John 10 I am the good shepherd.
Then, in John 21, Jesus, following His Resurrection, which followed His building His Church upon Peter, the Rock, Jesus taeches us He is making Peter the Shepherd. And ONLY Peter. Jesus says these words only to Peter.
When therefore they had dined, Jesus saith to Simon Peter: Simon son of John, lovest thou me more than these? He saith to him: Yea, Lord, thou knowest that I love thee. He saith to him: Feed my lambs. He saith to him again: Simon, son of John, lovest thou me? He saith to him: Yea, Lord, thou knowest that I love thee. He saith to him: Feed my lambs. He said to him the third time: Simon, son of John, lovest thou me? Peter was grieved, because he had said to him the third time: Lovest thou me? And he said to him: Lord, thou knowest all things: thou knowest that I love thee. He said to him: Feed my sheep.
*Can one be a practicing faithful Christian if one respudiates the authority established by Jesus? (Peter and his sucessors)
The Old Testament is fulfilled in the new and the archtypes present in the OT are revealed in full in the New Testament. The pattern is clear for those with eyes to see
You quotation of our Lord and Savior isn't as forceful as its meaning provided to the believer by the Father.
And ONLY Peter

Brazen extrapolations and inferences are very hazardous things to build even minor doctrine on.
Christ said some things ONLY to John the Beloved. I wonder what layers of extrapolated, inferred doctrines we could build on such ONLY statements.
