The mystery of the Holy Trinity, namely, that the one God exists eternally in the three persons: Father, Son and Holy Spirit; and has so revealed Himself to us in the Gospel.
The full deity and full humanity of our Lord Jesus Christ, God Incarnate, who by reason of His birth of the Virgin Mary, sinless life, atoning death, bodily resurrection, glorious ascension and triumphant reign, is the only Mediator between God and man.
The trustworthiness of the canonical books of the Old and New Testaments as “God’s Word written,” which contain all things necessary for salvation, teach God’s will for his world, and have supreme authority for faith, life and the continuous renewal and reform of the Church.
The justification of the repenting and believing sinner is God’s gracious act of declaring him righteous on the grounds of the reconciling death of Christ, who suffered in our place and rose again for us; and sanctification as the gracious continuing activity of the Holy Spirit in the justified believer, perfecting his repentance, nurturing the new life implanted within him, transforming him into Christ’s image, and enabling him to do good works in the world.
The Church as the Body of Christ, whose members belong to the new humanity, is called to live in the world in the power of the Spirit, worshipping God, confessing His truth, proclaiming Christ, supporting one another in love and giving themselves in sacrificial service to those in need.
The calling of all Christians to exercise their God-given gifts in ministry, and to work, witness, and suffer for Christ; together with the particular calling of ordained ministers, who, by preaching, teaching and pastoral care, are to equip God’s people for His service, and to present them mature in Christ.
-William Temple, Archbishop of Canterbury (1942–1944)
