Are you a spiritual person? A mature Christian? The apostles do not think that you are unless you have mastered the basic principles of the oracles of God. The writer of the book of Hebrews wanted to present some exciting thoughts about Jesus. He wanted to start exploring some heady insights about the work of Messiah, but he felt frustrated because people seemed unprepared for these deeper, spiritual lessons. He wanted to go deep, but people were still shallow. They did not have the basics down. He wrote, "It is hard to explain, since you have become dull of hearing. For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food" (Hebrews 5:11-12). In Elementary Principles, D. Thomas Lancaster takes listeners back to first-century Messianic Judaism to explore what he calls "an apostolic catechism", the foundational basics of discipleship to Jesus of Nazareth. Think you know it all already? Get ready to rethink your religion. This book of "basics" challenges common Christian assumptions while laying out clear, biblical definitions for all followers of Jesus. For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food. (Hebrews 5:11-12)
