The Presbyterian Church of Nigeria is a part of the Holy Catholic or Universal Church. It is one of the results of the Protestant Reformation that was begun in 1517 AD. It worships one God Almighty, in the Trinityof the Father, the Son and the Holy Spirit. It rejoices in the sovereign grace of God towards humanity and creation and confesses our Lord Jesus Christ as the eternal Son of God who was crucified for the salvation of humankind and who is the Head of the Universal Church. It believes in the Word of God as contained in the scriptures of the Old and New Testaments as its supreme rule of faith and life. The Church proclaims the gospel of the kingdom of God and invites all to receive the forgiveness of sins and the acceptance by God through faith in Jesus Christ and the gift of eternal life
