No other answer was seriously possible. In the very act of ostentatiously terming Tindal an "infidel," Middleton describes an answer made to him by the apologist Chapman as a sample of a kind of writing which did "more hurt and discredit" to Christianity "than all the attacks of its open adversaries." [867] In support of the miracles of the gospel and the apostolic history he offers merely conventional pleas: against the miracles related by the Fathers he brings to bear an incessant battery of destructive criticism. We may sum up that by the middle of the eighteenth century the essentials of the Christian creed, openly challenged for a generation by avowed deists, were abandoned by not a few scholars within the pale of the Church, of whom Middleton was merely the least reticent. After his death was published his Vindication of the Inquiry (1751); and in his collected works (1752) was included his Reflections on the Variations or Inconsistencies which are found among the Four Evangelists, wherein it is demonstrated that "the belief of the inspiration and absolute infallibility of the evangelists seems to be more absurd than even that of transubstantiation itself." [868] The main grounds of orthodoxy were thus put in doubt in the name of a critical orthodoxy. In short, the deistic movement had done what it lay in it to do. The old evangelical or pietistic view of life was discredited among instructed people, and in this sense it was Christianity that had "decayed." Its later recovery was economic, not intellectual. Thus Skelton writes in 1751 that "our modern apologists for Christianity often defend it on deistical principles" (Deism Revealed, pref. p. xii. Cp. vol. ii, pp. 234, 237).
