Original sentence: Jehovah's Witnesses, a prominent Nontrinitarian religious group, contend that the perplexity of the Trinitarian arguments is reason enough to reject the doctrine of the Trinity
Edited sentence: Jehovah's Witnesses believe it is a contradiction to simultaneously say that knowing "the only true God" (John 17:3) is a requirement of everlasting life, and that God is an unknowable "mystery".Nontrinitarians claim that the perplexity of the Trinitarian arguments, which have included the use of philosophy, is contrary to the Biblical principles of simplicity and clarity in doctrine..
