Sacramental Negligence: The failure to uphold the biblical requirements for partaking in the Lord's Supper, treating it as a mere ritual rather than a sacred ordinance requiring discernment.

While the sermon effectively highlights the biblical mandate for fellowship and the dangers of isolation, it fundamentally compromises the Gospel by presenting church attendance and relational effort as the primary mechanism for spiritual survival. The message shifts from 'we fellowship because we are saved' to 'we must fellowship to stay saved,' introducing a dangerous moralism that undermines the sufficiency of Christ's finished work and the sovereign power of the Holy Spirit.

Biblical Parallel (Archetype): Thyatira — The sermon exhibits active doctrinal drift by blending orthodox truths about community with a fundamental heresy of moralism. It elevates human behavioral conformity and ecclesiastical routine to the status of spiritual necessity, effectively teaching that isolation leads to spiritual death. This constitutes a corruption of the Gospel Engine, replacing the monergistic work of the Holy Spirit with a synergistic requirement for human effort and attendance.
