I don't know much about the Anglican faith regarding "purification of women." Sounds pretty dated, I imagine.
Knox would be called a Presbyterian today. In his time Presbyterian referred to the method of church governance that was founded on the Reformed teaching of John Calvin in Geneva which Knox studied and brought back to Scotland.
In our Presbyterian church we sit in the pews in order to partake of the grace of the Lord's Supper while the bread and wine are passed throughout the congregation. Here's a good link:
Isn't the Internet amazing? 8~)
By the way, not to criscross threads or anything, but Warfields explanation of the Reformed Faith was a very good read. Here are the parts I found myself breathing that breath of rest to:
13. I believe that God has redeemed His people unto HimseIf through Jesus Christ our Lord; who, though He was and ever continues to be the eternal Son of God, yet was born of a woman, born under the law, that He might redeem them that are under the law; I believe that He bore the penalty due to my sins in His own body on the tree, and fulfilled in His own person the obedience I owe to the righteousness of God, and now presents me to His Father as His purchased possession, to the praise of the glory of His grace forever; wherefore renouncing all merit of my own, put all my trust only in the blood and righteousness of Jesus Christ my redeemer.
14. I believe that Jesus Christ my redeemer, who died for my offenses was raised again for my justification, and ascended into the heavens, where He sits at he right hand of the Father Almighty continually making intercession for his people, and governing the whole world as head over all things for His Church; so that I need fear no evil and may surely know that nothing can snatch me out of His hands and nothing can separate me from His love.
15. I believe that the redemption wrought by the Lord Jesus Christ is effectualy applied to all His people by the Holy Spirit, who works faith in me and thereby unites me to Christ, renews me in the whole man after the image of God, and enables me more and more to die unto sin and to live unto righteousness; until His gracious work having been completed in me, I shall be received into glory; in which great hope abiding, I must ever strive to perfect holiness in the fear of God.
19. I believe that the visible Church consists of all those who are united to Christ, the Head of the Church, by profession of their faith, together with their children; and that the visible unity of the body of Christ, though obscured, is not destroyed by its division into different denominations of professing Christians. Therefore I believe that all of these which maintain the Word and Sacraments in their fundamental integrity are to be recognized as true branches of the Church of Jesus Christ.
20. I believe that God alone is Lord of the conscience and has left it free from the doctrines and commandments of men, which are in any respect contrary to His Word, or beside it in matters of faith or worship. I believe therefore, that the rights of private judgment in all matters that respect religion are universal and inalienable and that no religious constitution should be supported by the civil power, further than may be necessary for protection and security equal and common to all others.
21. I believe that the Church is God's spiritual minister for the purpose of redemption and the state is God's providential minister for the purpose of thisworldly order. The power of the Church is exclusively spiritual; that of the State includes the exercise of force. The constitution of the Church derives exclusively from divine revelation; the constitution of the State must be determined by human reason and the course of providential events. I believe therefore that the Church has no right to construct or modify a government for the State, and the State has no right to frame a creed or polity for the Church.
22. I believe that disciples of Jesus Christ are called to be His witnesses in the world, proclaiming the justice and mercy of God to all men, and making evident His wise and righteous rule over every aspect of human culture. Therefore it is my obligation to search the Scriptures with all the skills God has allotted me, and to seek, within the bounds of my calling, to apply my understanding of His Word to the entire created order, and to all the outworkings of His most wise providence. And I believe that it is my privilege and duty to pursue a vocation in this world that employs my gifts to the glory of God, and for the good of my family, my congregation, my community, and, as God brings opportunity, to any who may be in need.
