You make interesting observations, not a captive, but the reality is that within a short time after the death of Jesus we find clear evidence of a formal structure within the Christian community with the Apostles at the head. These are the same Apostles that were granted authority to loose and bind by the power of the holy spirit.
#1 He chose humans to carry out his work. At Matthew 16:18, Jesus selected Peter as the first among the Apostles:
"You are Rock and on this rock I will build my Church." (Matthew 16: 18)
When you build, not a captive, you are creating a structure.
#2 He gave the Apostles authority to carry out his work:
"Whatever you bind on earth will be bound in heaven."(Matthew 16:19; 18:18)
"Receive the Holy Spirit, whose sins you forgive, they are forgiven, whose sins you retain, they are retained."(John 20:23)
#3 Jesus gave Peter and the Apostles a clear idea as to what work they would do.
He told them to celebrate the last supper in his memory. (Luke 22:19 He told them to make disciples of all the nations. (Matthew 28:19) He told them to proclaim the Gospel to every person in the world. (Mark 16:15)
#4 The Church, as founded by Jesus, was hierarchical. At Acts 15, we see how the Apostles and elders came together to decide upon a matter regarding the new Gentile believers. Their decision was binding on the Church as a whole. In Paul's letters, we see clear instructions regarding appointment to positions of authority in individual churches (Presbyteros and Diaconos). Paul himself, along with the rest of the Apostles that wrote letters, spoke with authority--an authority vested in their Apostolic office. This is irrefutable.
Jesus founded a Church to teach His people and proclaim the Gospel. Through the Holy Spirit, he helped the Apostles create an organizational structure for the Church. It is clear that it was Jesus' intention to do so, and it is clear that the Apostles carried out his intentions after his rising.
....if I am delayed, you will know how people ought to conduct themselves in God's household, which is the church of the living God, the pillar and foundation of the truth.....(1 Tim 3:15)
