It was very necessary for the early church to stand against doctrinal errors, such as Arianism and Sabellianism but, in the doing so, some chose to state a creed (the Athanasian Creed), rather than simply make reference to original scripture and it could be argued that the Athanasian Creed came to be regarded as 'scripture'.
Since the seventeenth century the Westminster Confession (and in its other forms, the Savoy Declaration and similar) has become the so-called 'subordinate standard' by which serious Christians (who acknowledge doctrinal issues and acknowledge the necessity of taking a stand on them) state their doctrine.
But is it the case, over the past few centuries, that the Westminster Confession has, in fact, become 'The Standard' and that the scripture has been relegated to a subordinate place ?
The Free Presbyterian website argues :
When a Confession corresponds to Scripture as an account of the Church’s understanding of what the truth of God is, it is quite out of place to suggest that requiring allegiance to the Confession is interfering with allegiance to the Word of God. For those who recognise the authority of God’s Word as the revelation of His will in every matter, a Confession of Faith is not a substitute for Scripture but a necessary expression and summary of what Scripture teaches.
The Free Church of Scotland states :
Ever since the earliest days of the church, Christians have laid out their beliefs in brief ‘creeds’ or ’confessions’ in an attempt to summarise essential Christian truths and to guard the church from error. These statements are always secondary to the Bible but they are enormously helpful. A full summary of our teaching is found in the Westminster Confession of Faith.
The Church of Scotland goes even further :
The full Confession of Faith was agreed upon by the Assembly of Divines at Westminster and examined and approved in 1647 by the General Assembly of the Church of Scotland and ratified by Acts of Parliament in 1649 and 1690.
[Note the word "ratified"...OED 'To confirm or validate (an act, agreement, gift, etc.) by giving formal consent, approval, or sanction.']
So the first requires my 'allegiance' to the WC.
The second say that 'a full summary of their teaching is within it' (thus, they have not added to their teaching for three hundred and seventy years).
And the third advise me that the British Government have 'ratified' it.
Has, indeed, the Westminster Confession been accepted as 'The Standard' in the Protestant assemblies, to which the text of scripture must take a subordinate place ?
