Adolf von Harnack,
History of Dogma, Volume 2
“ The prophets and Christ are therefore a source of righteousness in so far as they are teachers. But as God, that is, the divine Word (which we need not here discuss) has spoken in them, Christianity is to be defined as the Knowledge of God, mediated by the Deity himself, and as a virtuous walk in the longing after eternal and perfect life with God, as well as in the sure hope of this imperishable reward. By knowing what is true and doing what is good man becomes righteous and a partaker of the highest bliss. ”
