 Also in his discussion of trinitarian and Christological issues he warns theologians not to naively follow the rules of logic without bearing possible misunderstandings in mind. Although the sentence ‘Christ is only God’ is logically true because Christ is God and no other person born on earth but Christ is God, it is dangerous to accept this sentence without further qualifications, Marsilius argues, because it seems to confirm the view of those heretics who claim that Christ was without a human nature, as the word ‘only’ can be understood to exclude humanity when added to the word  ‘God’.[33]
