📖 Biblical Definition
Biblical Theology (as a method) is the discipline that traces the unfolding of biblical themes — covenant, kingdom, temple, priesthood, sacrifice, exodus, exile-and-return, Spirit, son-of-Man, bride — through the canon’s redemptive-historical storyline. It reads Scripture diachronically (across time), tracing how each theme develops from Genesis to Revelation and climaxes in Christ. It is distinct from Systematic Theology (which gathers all biblical teaching under doctrinal categories — God, man, sin, salvation, last things) but complements it. Modern foundational figures include Geerhardus Vos, Edmund Clowney, Graeme Goldsworthy, D. A. Carson, and Sidney Greidanus. "And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself" (Luke 24:27) is the method’s charter.

⚠️ Modern Corruption
Modern systematic theology often outpaces biblical theology in evangelical training; both are needed, and biblical theology is the corrective against doctrinal abstraction.

Systematic Theology asks: what does the Bible teach about X? Biblical Theology asks: how does the theme X unfold across redemptive history? Both are legitimate; both are needed; the first depends on the second for its raw material.
The household's Bible reading deepens with biblical-theological awareness. The temple theme runs from Eden through tabernacle through Solomon's temple through Christ's body through the church through the new Jerusalem — one theme, eight major movements, climaxing in Revelation 21:22 (I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it).
🔗 Greek & Hebrew Roots
Greek theologia (theology) plus the qualifier ‘biblical’.

Greek theologia — speech about God.
Note: distinct from biblical theology as ‘theology that is biblical’ (a much vaguer use).
Usage
"Systematic asks what; Biblical asks how it unfolds."
"Both are needed; the first depends on the second."
"One theme, multiple movements, climax in Christ."
