This sermon from 1585 was one of those that triggered Travers attack and appeal to the Privy Council. Travers accused Hooker of preaching doctrine favourable to the Church of Rome when in fact he had just described their differences emphasising that Rome attributed to works "a power of satisfying God for sin;..." For Hooker, works were a necessary expression of thanksgiving for unmerited justification by a merciful God. Hooker defended his belief in the doctrine of Justification by faith, but argued that even those who did not understand or accept this could be saved by God.
