“And awe came upon every soul, and many wonders and signs were being done through the apostles.” (Acts 2:43)
Our teaching ministries are all based on the apostles' teaching of the early Church. This teaching has been recorded and preserved for us in the Bible. The Old Testament contains the Scriptures that made up the Bible at the time of Jesus the apostles. The New Testament is the collection of apostolic writings that the Church deems to be authoritative.
Together, the Old and New Testaments are the complete Word of God and, thus, the curriculum of the Church for all teaching.
"All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work." (2 Timothy 3:16-17)
