Post Tenebras Lux (Latin: “Light after Darkness”). Originally adopted by the city of Geneva during the days of John Calvin, this Latin phrase eventually came to symbolize the Protestant Reformation as a whole. In truth, the Protestant Reformation constitutes one of the most glorious and earth-shaking movements of the Holy Spirit in the history of the world. This momentous event saw the recovery of the biblical Gospel, the widespread dissemination of sound biblical doctrine, the refutation of Catholic Rome’s errors, the study of the biblical text in the original languages, and the translation of the Scriptures into the ‘common’ languages. Eventually, the theological principles of the Reformation became crystallized into the Protestant Solas: (1) sola Scriptura (Latin: “by the Scriptures alone”); (2) sola fide (Latin: “by faith alone”); (3) sola gratia (Latin: “by grace alone”); (4) solo Christo (Latin: “by Christ alone”); (5) soli Deo gloria (Latin: “to God alone be the glory”); (6) solo evangelio (Latin: “by the Gospel alone”); (7) solo cruce (Latin: “by the cross alone”); and (8) solo Spiritu (Latin: “by the Spirit alone”). The purpose of this blog series is to equip believers (both young and mature) with a concise summary of each of the Protestant Solas, as well as the Scriptural foundation for each.
Solo Christo is also frequently rendered solus Christus in Latin.
