Episode notes
Devotion To Apostolic Teaching Defined Early Faith
- The early Christians devoted themselves warmly to apostolic teaching as their first expression of faith.
- Scott Clark explains this devotion moved believers toward the communion of the saints, not away from other Christians, as the church's defining pattern.
Preaching Is The Instrument Of Faith
- Faith comes through hearing the preached gospel and preaching is central to the church's mission.
- Clark cites Romans 10 to show hearing requires sent preachers, and that Reformed churches practice twice-weekly preaching as the Spirit's instrument to create faith.
Pair Preaching With Sacraments In Worship
- Use both preaching and the sacraments to form and confirm faith in worship.
- Clark references Heidelberg Catechism Q65: the Spirit works faith by preaching and confirms it by sacraments, demonstrated in Acts 2's pattern of baptism then regular worship.
