The RCCG affirms the virgin birth of Jesus Christ as a fundamental and non-negotiable doctrine of Christian faith. Mary conceived Jesus miraculously by the power of the Holy Spirit, without a human father. This miracle demonstrates God's power and confirms Jesus as the divine Son of God. The virgin birth is a sign of God's entry into history and the inauguration of salvation.

Mary is honored as the blessed mother of the Lord and is venerated in RCCG practice, though the church does not accept Catholic Marian doctrines such as the Immaculate Conception or the Assumption of Mary as church dogma. Mary is respected as a model of faith and obedience, but prayers are not directed to Mary, and she is not invoked as a mediator. Jesus alone is confessed as the mediator between God and humanity. The virgin birth is celebrated in the RCCG's observance of Christmas and is integral to Christological faith.
