Evelyn's Diary. 12 Apr 1689. Scotland declares for King William (age 38) and Queen Mary (age 26), with the reasons of their setting aside King James (age 55), not as abdicating, but forfeiting his right by maladministration; they proceeded with much more caution and prudence than we did, who precipitated all things to the great reproach of the nation, all which had been managed by some crafty, ill-principled men. The new Privy Council have a Republican spirit, manifestly undermining all future succession of the Crown and prosperity of the Church of England, which yet I hope they will not be able to accomplish so soon as they expect, though they get into all places of trust and profit.
Evelyn's Diary. 12 Apr 1689. King James (age 55) was now certainly in Ireland with the Marshal d'Estrades, whom he made a Privy Councillor; and who caused the King (age 55) to remove the Protestant Councillors, some whereof, it seems, had continued to sit, telling him that the King of France (age 50), his master, would never assist him if he did not immediately do it; by which it is apparent how the poor Prince (age 55) is managed by the French.
Evelyn's Diary. 12 Apr 1689. I went with the Bishop of St. Asaph (age 61) to visit my Lord of Canterbury (age 58) at Lambeth [Map], who had excused himself from officiating at the coronation, which was performed by the Bishop of London (age 57), assisted by the Archbishop of York (age 74). We had much private and free discourse with his Grace (age 58) concerning several things relating to the Church, there being now a bill of comprehension to be brought from the Lords to the Commons. I urged that when they went about to reform some particulars in the Liturgy, Church discipline, Canons, etc., the baptizing in private houses without necessity might be reformed, as likewise so frequent burials in churches; the one proceeding much from the pride of women, bringing that into custom which was only indulged in case of imminent danger, and out of necessity during the rebellion, and persecution of the clergy in our late civil wars; the other from the avarice of ministers, who, in some opulent parishes, made almost as much of permission to bury in the chancel and the church, as of their livings, and were paid with considerable advantage and gifts for baptizing in chambers. To this they heartily assented, and promised their endeavor to get it reformed, utterly disliking both practices as novel and indecent.
