Augustine's understanding of signs includes several hermeneutical presuppositions as important factors. First, the interpreter should proceed with humility, because only a humble person can grasp the truth of Scripture (DDC 2.41.62). Second, the interpreter must have a spirit of active inquiry and should not hesitate to learn and use pagan education for the purpose of leading to Christian learning, because all truth is God's truth (DDC 2.40.60-2.42.63). Third, the heart of interpreter should be founded, rooted, and built up in love which is the final goal of the entire Scriptures (DDC 2.42.63).
