I observe the great and wonderful mistake, both our own and our fathers, as to the civil powers of this world, acting in spiritual matters. I have read … the last will and testament of the Lord Jesus over many times, and yet I cannot find by one tittle of that testament that if He had been pleased to have accepted of a temporal crown and government that ever He would have put forth the least finger of temporal or civil power in the matters of His spiritual affairs and Kingdom.
Hence must it lamentably be against the testimony of Christ Jesus for the civil state to impose upon the souls of the people a religion, a worship, a ministry, oaths (in religious and civil affairs), tithes, times, days, marryings, and buryings in holy ground...
