We have a leader of the church. It's Christ, who appointed some to be elders and teachers and administrators, etc.
Christ is the head, not any one man, or any man. There's a difference between being the leader and overseer.
That they may be one.....Jesus prayed in John 17
One Lord, one faith, one baptism.....Paul in Ephesians 4
When did the Church become no longer one? When did Christians no longer share the same faith?
When the authority of the pope and the Church was rejected.
The Church needs a leader who is appointed by the head who is Jesus Christ.
One may believe they have no need of anyone but themselves and their Bible, but that is not the way that Jesus and His first followers believed.
Yet the LORD gave Peter a special calling, as it is written: And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven. And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
This is now the third time that Jesus shewed himself to his disciples, after that he was risen from the dead. 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. He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep. He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep. Verily, verily, I say unto thee, When thou wast young, thou girdest thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not. This spake he, signifying by what death he should glorify God. And when he had spoken this, he saith unto him, Follow me.
We need to have a care that we are sheep and not goats.
