In the early days of the Church Paul dealt with many problem within the various churches. After Paul was gone I’m sure it wasn’t much easier for the ministers to continue in the practices that were laid down for them by the apostles. Christ gave the right of laying down the foundation of the church to the apostles. Ephesians 2:20. Now within the foundation of the church you would find the doctrine and practice of the church and God’s people. So if the foundation was given to the Apostles who has the right to add on to His Church. I would have to say only the Apostles. I’m pretty sure that there aren’t any more of them around today. So the Apostles set it up being guided by what Christ had taught them and being lead by the Holy Spirit. It is the duty of all of God called ministers to uphold the doctrine and practices that was set up by the apostles and not sway from them even if they think they have a better way. No man can improve upon what God has done. Our thoughts are not God’s thoughts, and our ways are not His ways. May the true doctrine and practice stand firm until our Saviour returns. He said it would and that is good enough for me. 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.
Philip
