What This Free Course Covers

This free course considers several difficult questions about salvation, apostasy, repentance, and church membership through the lens of early Christian teaching. The lessons address whether someone who falls away after baptism can still return, how the early Christians treated serious sins after baptism, and why repentance remained central even when church discipline could be strict.

The course also looks at claims that salvation depends on loyalty to one modern organization or church body, contrasting those claims with Scripture, the historic faith, and the context of Ignatius’ instructions about obeying church leaders. A longer lesson focuses on Hebrews 10:26 and the warning that “there no longer remains a sacrifice for sins,” explaining how early Christians took the passage seriously while also considering the wider New Testament teaching on repentance and forgiveness.

Together, the lessons are sober, practical, and careful with passages that are often misunderstood or used in fear-driven ways.
