What is the Apostles' Doctrine according to the Bible?

The Apostles' Doctrine consists of teachings that emphasize the centrality of Christ and His work of redemption. In Acts 2:42, we read that the early church 'continued steadfastly in the apostles’ doctrine and in fellowship, and in breaking of bread, and in prayers.' This clearly shows that the apostles focused on teaching about Jesus as the Messiah, His death, and resurrection as the essence of the gospel message. The doctrines of grace, which articulate that salvation comes through faith alone in Christ alone, echo throughout the New Testament. This apostolic teaching remains the foundation for church doctrine, fostering unity among believers as they celebrate the gospel together.
