The RCCG teaches that Jesus Christ died as a substitutionary sacrifice for the sins of humanity. Christ bore the penalty (the wrath of God) that humanity deserved, making it possible for believers to be forgiven and reconciled to God. The death of Christ is understood as a ransom or payment for sin, through which Christ secured redemption for all who believe. This penal substitutionary framework is central to RCCG soteriology and is frequently emphasized in preaching and teaching.

A distinctive feature of RCCG theology is the integration of Christ's atonement with divine healing. The church teaches that in Christ's atonement, provision is made not only for the forgiveness of sins but also for the healing of physical sicknesses and diseases. This interpretation draws on Isaiah 53:4-5, understood as encompassing both spiritual forgiveness and physical healing. The RCCG's emphasis on divine healing as part of the atonement reflects the church's pastoral concern for the holistic wellbeing of believers and aligns with its prosperity gospel emphasis.
