Of the Body of Scripture, and Theology.
The Body of Scripture is a doctrine sufficient to live well.
It comprehendeth many holy sciences, whereof one is principal, others are handmaids or retainers.
The principal science is Theology.
Theology is the science of living blessedly for ever. Blessed life ariseth from the knowledge of God:
John 17:3
This is life eternal, that they know thee to be the only very God, and whom thou hast sent Christ Jesus.
Isaiah 53:11
By his knowledge shall my righteous servant (viz. Christ) justify many.
And therefore it ariseth likewise from the knowledge of ourselves, because we know God by looking into ourselves.
Theology hath two parts: the first of God, the second of his works.
