How do we know the doctrine of antanaclasis is true?

The validity of antanaclasis as a doctrine is reinforced through its manifestation in several biblical texts. For instance, in Matthew 26:29, Jesus' phrase about not drinking of the vine again has a literal interpretation regarding the wine and a metaphorical significance related to the eschatological feast in the Kingdom of Heaven. This duality in meaning can be applied across other verses too, where terms are deliberately chosen to expand comprehension of spiritual truths.

Furthermore, the examination of these passages within their broader context provides theological integrity to the doctrine. For example, Romans 2:28-29 elucidates that not all who are descended from Israel according to the flesh are of true spiritual Israel. Here, the concept of 'Israel' varies in application, reflecting God's covenantal plan and His choice of the elect. Such textual analysis illustrates how antanaclasis reveals profound truths about human nature and divine sovereignty, affirming the doctrine’s relevance in the study of Scripture.
