Distinctive ministerial emphases
The necessity of regular Gospel preaching
He has repeatedly lobbied for the necessity of distinctive and frequent evangelistic addresses, and lamented the loss of this basic duty amongst evangelical ministers. His own church has a specific evangelistic service at 6.30pm on Sundays.
Separatism
By calling other ministers to remember and consider the Downgrade Controversy, Peter Masters has advocated a duty of ministerial separation from churches which have defected from basic precepts of historical evangelical doctrine, like the necessity of regeneration, justification by faith without works, or the infallibility and sufficiency of the Bible for church rule. In this he has repeated the call of Martyn Lloyd-Jones, in his controversy with John Stott, to separate from non-evangelical churches, and followed in the tradition of E. J. Poole-Connor, the original founder of the Fellowship of Independent Evangelical Churches.
Charismatic movement
He has opposed and challenged the teaching of the Charismatic Movement that New Testament sign gifts are still extant, arguing that the Bible contains the promise that it is both sufficient and complete, rendering new revelation both redundant and dangerous. This position has been described as cessationist. He has, upon the same grounds, critiqued claims of the gift of miraculous healing as spurious, lacking credibility and sometimes occultic.
He opposes Neo-Darwinian evolution, which evangelicals have seen historically as a form of humanist propaganda, and as a doctrine viewed as wholly at variance with the first books of the Bible. He helped found the Newton Scientific Association, and has supported lectures and talks examining weaknesses of the theory.
