Welcome to Episode 40 of the Greg SCHREFFLER Show™. Today, as we conclude this faith study series, we shift our focus to how the early church confronted doctrinal challenges, preserved truth, and ultimately guided the formation of the New Testament canon.

Up to this moment, the church has been built, tested, and expanded—through apostles, persecution, structure, and discipline. But now, a new threat emerges. Not from Rome. Not from open opposition.
From within.
What begins as distortion will become system.
What begins as deviation will become doctrine.
And what challenges the church will ultimately force it to clarify what it truly believes.
Because truth, if it is not guarded, will be redefined.

By the early second century, Churches are multiplying across the Roman world, and those communities now had to establish leadership, guard sound teaching, and preserve the message that had been handed down to them.
The church may have survived persecution. Now it had to navigate growth.
This episode begins at that turning point; when the expanding church must learn how to remain faithful while becoming successful; much larger than the small movement that first began in Jerusalem.
