The core ideas and teachings of Jesus Christ’s apostles as described in the New Testament are referred to as Apostolic Doctrine. It comprises doctrines on God’s nature, the divinity of Jesus Christ, the Holy Spirit, salvation, baptism, the church, and Christ’s second coming. The Apostolic Doctrine emphasizes the importance of having personal contact with God, living a pure life, and spreading the gospel message. It is regarded as the foundation of the Christian faith and is still taught in many churches today.
