Faith is a precious doctrine of the gospel of Jesus Christ. Ancient prophets and apostles clearly taught that faith is relational: faith is trust, loyalty, obedience, and devotion to God and his Son, and it encompasses God’s blessings to us. In the language and culture of ancient Greece, pistis (faith) meant faithfulness and trust, and when New Testament writers taught about faith, their ancient readers understood its relational nuances.
An apostasy regarding the meaning and doctrine of faith occurred, and the word faith came to have many varied meanings. Some theologians have taught that faith is a passive belief in a creed or a statement of belief in God that would guarantee one’s salvation. Theologians such as Augustine, Aquinas, Wyclif, Hus, Luther, Calvin, and Bultmann went of course in their understanding of faith.
The restoration of the gospel that came through Joseph Smith and living prophets has revived the correct understanding of faith as a reciprocal relationship between people and God. For Latter-day Saints, faith is a principle of action, knowledge, understanding, trust, obedience, and faithfulness. Faith once again motivates disciples to trust in Jesus Christ, repent, and follow his straight and narrow covenant path leading to salvation and exaltation.
