Charles I of England
Charles I (19 November 1600 – 30 January 1649) was King of England, King of Scotland, and King of Ireland from 27 March 1625 until his execution in 1649. He was born into the House of Stuart as the second son of King James VI of Scotland, but after his father inherited the English throne in 1603 (as James I), he moved to England, where he spent much of the rest of his life. He became heir apparent to the three kingdoms of England, Scotland and Ireland in 1612 on the death of his elder brother Henry Frederick, Prince of Wales. An unsuccessful and unpopular attempt to marry him to the Spanish Habsburg princess Maria Anna culminated in an eight-month visit to Spain in 1623 that demonstrated the futility of the marriage negotiations. Two years later he married the Bourbon princess Henrietta Maria of France.
Charles I of England
After his succession in 1625, Charles quarrelled with the Parliament of England, which sought to curb his royal prerogative. Charles believed in the divine right of kings, and was determined to govern according to his own conscience. Many of his subjects opposed his policies, in particular the levying of taxes without parliamentary consent, and perceived his actions as those of a tyrannical absolute monarch. His religious policies, coupled with his marriage to a Roman Catholic, generated antipathy and mistrust from Reformed religious groups such as the English Puritans and Scottish Covenanters, who thought his views were too Catholic. He supported high church Anglican ecclesiastics such as Richard Montagu and William Laud, and failed to aid continental Protestant forces successfully during the Thirty Years' War. His attempts to force the Church of Scotland to adopt high Anglican practices led to the Bishops' Wars, strengthened the position of the English and Scottish parliaments, and helped precipitate his own downfall.
Caroline Divines
The Caroline Divines were influential theologians and writers in the Anglican Church who lived during the reigns of King Charles I and, after the Restoration, King Charles II (Latin: Carolus). There is no official list of Caroline-era divines; they are defined by the era in which they lived, and Caroline Divines hailed from England, Ireland, Scotland, and Wales. However, of these four nations, it is Caroline England which is most commonly considered to have fostered a golden age of Anglican scholarship and devotional writing, despite the socio-cultural upset of civil war, regicide, and military rule under Oliver Cromwell. Importantly, the term divine is restricted neither to canonised saints nor to Anglican figures, but is used of many writers and thinkers in the wider Christian church.
Caroline Divines
The corpus produced by the Caroline divines is diverse. What they have in common is a commitment to the faith as conveyed by Scripture and the Book of Common Prayer, thus regarding prayer and theology in a manner akin to that of the Apostolic Fathers and other later Christian writers. On the whole, the Caroline Divines view the via media of Anglicanism not as a compromise but "a positive position, witnessing to the universality of God and God's kingdom working through the fallible, earthly "ecclesia Anglicana"." These theologians regarded Scripture as authoritative in matters concerning salvation, although they drew upon tradition and reason as well, the latter in the form of deductive logic and the former with special reference to the Church Fathers. Politically, the Caroline Divines were royalists but primarily of a constitutional, rather than absolutist, bent.
