I hate to be this guy but the Westminster Standards sort of fly in the face of this idea.
The Confession of Faith defines the elements of worship as follows in Chapter 21.3-5 as follows:
"21.3 Prayer with thanksgiving, being one special part of religious worship, is by God required of all men; and that it may be accepted, it is to be made in the name of the Son, by the help of His Holy Spirit, according to His will, with understanding, reverence, humility, fervency, faith, love, and perseverance; and, if vocal, in a known tongue.
21.4 Prayer is to be made for things lawful, and for all sorts of men living, or that shall live hereafter; but not for the dead, nor for those of whom it may be known that they have sinned the sin unto death.
21.5 The reading of the Scriptures with godly fear; the sound preaching, and conscionable hearing of the Word, in obedience unto God with understanding, faith, and reverence; singing of psalms with grace in the heart; as, also, the due administration and worthy receiving of the sacraments instituted by Christ; are all parts of the ordinary religious worship of God: besides religious oaths, and vows, solemn fastings, and thanksgivings upon special occasion; which are, in their several times and seasons, to be used in an holy and religious manner."
As can be seen, corporate confession was not deemed an element of worship by the Westminster Assembly. Further, the Directory of Public Worship put Corportate Confession of Sin as part of the Prayer offered by the Minster and had no place for corporate confession of faith. Directory for Public Worship "Of Publick Prayer Before the Sermon" section opens with the following:
"AFTER reading of the word, (and singing of the psalm,) the minister who is to preach, is to endeavour to get his own and his hearers hearts to be rightly affected with their sins, that they, may all mourn in sense thereof before the Lord, and hunger and thirst after the grace of God in Jesus Christ, by proceeding to a more full confession of sin, with shame and holy confusion of face, and to call upon the Lord to this effect:"
This is further enforced by minutes from December 16th, 1644 at the assembly where we read:
"That Dr. Burgess inform the Honorable Houses of Parliament that the reason why the Assembly have sent up nothing in the [Westminster] Directory [for Public Worship] concerning the Creed and the Ten Commandments, is because they reserve it for the Directory for catechizing, where they conceive it will be most proper.”- Alexander Mitchell & John Struthers, Minutes of the Sessions of the Westminster Assembly of Divines (Edinburgh: William Blackwood & Sons, 1874), p. 21
*IF* you use the Westminster Standards as a Corporate Confession, you are definitely going against the design of the standards.
