Jesus is the head of the church
Ephesians 5 v. 23: ‘...the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Saviour.’
Ephesians 4 vv. 15-16: ‘...speaking the truth in love, we will in all things grow up into him who is the Head, that is, Christ. From him the whole body, joined and held together by every supporting ligament, grows and builds itself up in love, as each part does its work.
Every believer is a priest and a minister
Hebrews 10 vv. 19-22: ‘Therefore, brothers, since we have confidence to enter the Most Holy Place by the blood of Jesus, by a new and living way opened for us through the curtain, that is, his body, and since we have a great priest over the house of God, let us draw near to God with a sincere heart in full assurance of faith, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water.’
1 Peter 2 v. 9: ‘...you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of him who called you out of darkness into his wonderful light. Once you were not a people, but now you are the people of God; once you had not received mercy, but now you have received mercy.’
Revelation 1 vv. 5-6: ‘To him who loves us and has freed us from our sins by his blood, and has made us to be a kingdom and priests to serve his God and Father – to him be glory and power for ever and ever! Amen.’
Leadership exists to:
Ephesians 4 v. 12: ‘...to prepare God’s people for works of service, so that the body of Christ may be built up.’
1 Corinthians 12 vv. 12-31: 'Just as a body, though one, has many parts, but all its many parts form one body, so it is with Christ. For we were all baptised by one Spirit so as to form one body — whether Jews or Gentiles, slave or free — and we were all given the one Spirit to drink. Even so the body is not made up of one part but of many. Now if the foot should say, “Because I am not a hand, I do not belong to the body,” it would not for that reason stop being part of the body. And if the ear should say, “Because I am not an eye, I do not belong to the body,” it would not for that reason stop being part of the body. If the whole body were an eye, where would the sense of hearing be? If the whole body were an ear, where would the sense of smell be? But in fact God has placed the parts in the body, every one of them, just as he wanted them to be. If they were all one part, where would the body be? As it is, there are many parts, but one body. The eye cannot say to the hand, “I don’t need you!” And the head cannot say to the feet, “I don’t need you!” On the contrary, those parts of the body that seem to be weaker are indispensable, and the parts that we think are less honourable we treat with special honour. And the parts that are unpresentable are treated with special modesty, while our presentable parts need no special treatment. But God has put the body together, giving greater honour to the parts that lacked it, so that there should be no division in the body, but that its parts should have equal concern for each other. If one part suffers, every part suffers with it; if one part is honoured, every part rejoices with it. Now you are the body of Christ, and each one of you is a part of it. And God has placed in the church first of all apostles, second prophets, third teachers, then miracles, then gifts of healing, of helping, of guidance, and of different kinds of tongues. Are all apostles? Are all prophets? Are all teachers? Do all work miracles? Do all have gifts of healing? Do all speak in tongues? Do all interpret? Now eagerly desire the greater gifts. And yet I will show you the most excellent way.'
