Salvation is the act of the Trinitarian God fulfilled through the Incarnation of the Logos — the Christ Jesus, who is the Saviour of all because He is the Creator of all.
Salvation of men from the power of sin, death and the Devil is the essential part of the Divine economy. The centre of it is the voluntary Passion and death on the Cross suffered by Christ, who by His Resurrection destroyed the power of Satan. The resurrected Body of Christ is the palpable mystery of oneness of the Church — since His Body is one. Catholicity of Christ’s Church is coextensive with the Orthodoxy of one Faith, »once delivered to the Saints«.
