[PAR35]

While a Protestant may well speak of the need to submit to the will of God, there is no test of this.

That is not correct. While the Scriptures provide the ultimate test, most protestant churches require obedience and submission. In the churches which follow the episcopal model (Episcopal, Methodist, Lutheran, to some extent the PCUSA, etc.) it isn't much different than what you see in the Roman Catholic church. In those which follow the Presbyterian form of government (Presbyterian, Reformed, etc.) , authority lies in the Presbyteries and Synods or Assemblies. Even in a congregational church (Baptists, Bible, Congregational), if you 'do your own thing' you are likely to find yourself disfellowshiped or excommunicated.

From the membership vows of one church: "Do you submit yourself to the government and discipline of the Church, and promise to study its purity and peace? "; for the candidate for licesure: "Do you promise to submit yourself, in the Lord, to the government of this Presbytery..."; for candidates for ordination: "Do you promise subjection to your brethren in the Lord".

[Petrosius]

The difference is that with Protestants they can first form their beliefs and then find a church that matches them. Each of these churches profess a belief that it is the Bible that is the sole rule of faith; the church just offers what it believes is the best interpretation. If someone should find themselves at odds with the teaching of a certain church they can move to one that more closely matches their beliefs or start their own. Thus church discipline is no real guide to evangelical life.
