Below, you will find an excerpt from Rev. Peter Toon’s The Anglican Way.  He spells out what it really means to be a reformer. The list he writes seems to be a prime example of what it means to be an orthodox church, as apposed to a heterodox church.

Catholic and Reformed

To affirm Catholicity means that we cannot be too selective in the way in which we look back to evaluate the long experience of the Church of God. A fault of most Protestant denominations has been, and remains, that of working from a limited perspective, choosing this and rejecting that. We are to accept the broad and sustained themes of Catholicity and to reject deviant and exaggerated developments and expressions.

When the reformers of the Church of England in the mid-sixteenth century attempted ‘to wash the dirty face’ of the national Church, they recognized and made a part of the Church’s reformed existence the following catholic emphases.

1. The priority and authority of the Scriptures as the source of our knowledge of God.

2. The doctrinal guidance of the Catholic Creeds-Apostles’, Nicene and Athanasian (Quicunque Vult).

3. The truth that salvation is, in the final analysis, the gift of God and by grace alone.

4. The use of Liturgy, which is faithful to Scripture and embodies the experience of the Church in worship over the centuries.

5. The historic episcopate or the order of bishops as a sign of the unity of the one Church of God. Unlike Scottish and Continental reformers, who ditched episcopacy because they saw it as too involved in the corruption which they knew must be removed, the English reformers insisted on the retention of the historic order of bishops.

6. The threefold ordained ministry of bishop, presbyter (= priest) and deacon, as that ministry which God has led the Church to adopt from primitive times.

7. The two Gospel sacraments of Holy Baptism and Holy Communion as instituted by Christ for regular use in the Church.

8. The unity of the ministry of the Word and Sacrament in the service of Holy Communion.

9. The need for regular preaching and teaching from the Scriptures.

10. The recognition that the visible unity of the Church on earth is God’s will.

11. The need for a regularly reviewed canon law and moral theology.

12. The priesthood of the whole Church as a worshipping and praying society.

The approach, which these emphases reflect, was called ‘reformed catholicity’.
