seen the Father, Jesus Christ is the only one who knows him and can reveal him.2
To believe in the Holy Spirit
152 One cannot believe in Jesus Christ without sharing in his
one can say Jesus is Lord, except by the Holy Spirit,22 who searches everything, even the depths of God... No one comprehends the thoughts of God, except the Spirit of God.23 Only God knows God completely: we believe in the Holy Spirit because he is God. The Church never ceases to proclaim her faith in one only God: 232 Father, Son and Holy Spirit.
III. The Characteristics of Faith Faith is a grace
living God,Jesus declared to him that this revelation did not come from flesh and blood, but from my Father who is in heaven.24 Faith is a gift of God, a supernatural virtue infused by him. Before this
who moves the heart and converts it to God, who opens the eyes
truth.25 Faith is a human act
154 Believing is possible only by grace and the interior helps of the Holy Spirit. But it is no less true that believing is an authen i~~g tically human act. Trusting in God and cleaving to the truths he has revealed is contrary neither to human freedom nor to human reason. Even in human relations it is not contrary to our dignity to believe what other persons tell us about themselves and their intentions, or to trust their promises (for example, when a man and a woman marry) to share a communion of life with one another. If this is so, still less is it contrary to our dignity to yield by faith the full submission of... intellect and will to God who reveals,26 and to share in an interior communion with him.
