Both a gift of God and a human act by which the believer gives personal adherence to God who invites his response, and freely assents to the whole truth that God has revealed. It is this revelation of God which the Church proposes for our belief, and which we profess in the Creed, celebrate in the sacraments, live by right conduct that fulfills the twofold commandment of charity (as specified in the ten commandments), and respond to in our prayer of faith. Faith is both a theological virtue given by God as grace, and an obligation which flows from the first commandment of God (26, 142, 150, 1814, 2087).
