The late Bishop of London Dr. Gibson's five pastoral letters to the people of his diocese; particularly to those of the two great cities of London and Westminster. The three first in defence of the Gospel-revelation, and by way of preservative against the late writings in favour of infidelity. The fourth against lukewarmness on one hand, and enthusiasm on the other. And the fifth and last on the late rebellion, and exciting to a serious reformation of life and manners. With a postscript setting forth the danger and mischiefs of popery.
