The Five Solas
Solus Christus
August 23, 2026
The sermon affirms solus Christus: Christ alone is the necessary and sufficient mediator whose once-for-all priestly sacrifice secures our acceptance before God, a truth the Reformers recovered from Scripture that calls believers to faithful obedience without substituting church rites or other mediators.
Summary
This morning's message on solus Christus emphasizes that Christ alone is both necessary and sufficient for salvation: his unique, permanent priesthood and once-for-all sacrifice mediate between God and humanity and ground our acceptance before God. The Reformers did not invent this doctrine but sought to recover and clarify the biblical teaching that Christ’s work is complete and cannot be supplemented by human performance, priests, saints, or rituals. While the church and means of grace remain important, they must serve Christ and never replace him; genuine grace produces obedience and transformed lives. The sermon concludes with a prayer of thanks for Christ’s perfect obedience and a call to greater faithfulness in response to belonging to him.
