Tertullian
Our Lord Jesus Christ, during His time on earth, engaged openly with the people and His disciples, of whom He selected twelve to serve as teachers to the nations. He directly addressed inquiries about His identity, affirming whether He was the Son of God, in what ways He was fully human, and in what ways He was divine. He clarified His role as a counselor of faith and a promise of eternal reward, defining what is and what has been; revealing the Father's will that He accomplishes, as well as what He commissions humanity to undertake. Who among us could rationally accept that His disciples, whom He appointed as instructors for the nations, who shared in His earthly journey, learned from Him, and lived in close fellowship with Him, could remain ignorant of truth? He personally elaborated on every matter that needed clarification, assuring them, "To you it is given to know the mysteries of the kingdom of heaven, but to them it is not given" (Matthew 13:11).
