As I know that you are not now to learn that chiefest particular duty of a king is to maintain the true religion (without which he can never expect to have God's blessing), so I assure you that this duty can never be right performed without the Church is rightly governed, not only in relation to conscience, but likewise for the necessary subsistence of the Crown. For, take it as an infallible maxim from me, that, as the Church can never flourish without the protection of the Crown, so the dependency of the Church upon the Crown is the chiefest support of regal authority. This is that which is so well understood by the English and Scots rebels, that no concessions will content them without the change of Church government, by which that necessary and ancient relation which the Church hath had to the Crown is taken away. Wherefore, my first direction to you is, to be constant in the maintenance of the episcopacy, not only for the reasons abovesaid, but likewise to hinder the growth of Presbyterian doctrine, which cannot but bring anarchy into any country, wherever it shall come for any time.

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "As I know that you are not now to learn that chiefest particular duty of a king is to maintain the true religion (without which he can never expect to have God's blessing), so I assure you that this duty can never be right performed without the Church is rightly governed, not only in relation to conscience, but likewise for the necessary subsistence of the Crown.

James Orchard Halliwell (1846), pp. 417-418" to mean that wisdom is timeless.
