As an Anglican Church our beliefs and teachings are grounded in the Holy Bible and articulated in the Historic Creeds, the Book of Common Prayer, the 39 Articles of Religion and the Ordinal (Article VI on the Supremacy and Sufficiency of the Holy Scriptures). Some of the key ideas can be summarised here:-
God
God is the triune God – one God in three persons, the Father, the Son and the Holy Spirit. God is sovereign in creation, revelation, redemption and final judgement. (Article I)
The Bible
The Bible, as originally given, is the inspired and infallible Word of God. The Old and New Testament Scriptures were authenticated by Jesus and are therefore the supreme authority for the Church in all matters of faith and conduct. (Article VI)
Sin
Since the fall, the whole of humankind is sinful and guilty and therefore subject to God’s wrath and condemnation. (Article IX)
Jesus
Jesus is perfectly and fully both God and man, with God in eternity but took to himself human nature at the incarnation by means of the virgin birth when two whole and perfect natures (Godhead and Manhood) were joined together in one person (Article II); his human life was sinless (Article XV); he died on the cross, was raised bodily from death and is now reigning over heaven and earth (Article III and IV).
Salvation
Sinful human beings are redeemed from the guilt, penalty and power of sin only through the sacrificial death of Christ their representative and substitute once and for all time. He is the only mediator between mankind and God. (Article XV and XVIII). Those who believe in Christ are pardoned all their sins and accepted in God’s sight only because of the righteousness of Christ credited to them; this justification is God’s act of undeserved mercy, received solely by trust in him and not by their own efforts. (Article XI)
The Holy Spirit
The Holy Spirit alone makes the work of Christ effective to individual sinners, enabling them to turn to God from their sin and to trust in Jesus Christ. He lives in all those he has regenerated. He makes them increasingly Christ-like in character and behaviour and gives them power for their witness in the world. (Article XVII).
The Church
The one holy catholic (ie universal) church is the Body of Christ, to which all true believers belong. (Article XIX)
The Return of Jesus Christ
The Lord Jesus Christ will return in person, to judge everyone, to execute God’s just condemnation on those who have not repented and to receive the redeemed to eternal glory. (Article IV)
