YOUCAT Question n. 22 - How does one go about believing?

(Youcat answer) Someone who believes is seeking a personal union with God and is ready to believe God in everything that he shows (reveals) about himself.     

A deepening through CCC

(CCC 150) Faith is first of all a personal adherence of man to God. At the same time, and inseparably, it is a free assent to the whole truth that God has revealed. As personal adherence to God and assent to his truth, Christian faith differs from our faith in any human person. It is right and just to entrust oneself wholly to God and to believe absolutely what he says. It would be futile and false to place such faith in a creature (Cf. Jer 17:5-6; Ps 40:5; 146:3-4). (CCC 151) For a Christian, believing in God cannot be separated from believing in the One he sent, his "beloved Son", in whom the Father is "well pleased"; God tells us to listen to him (Mk 1:11; cf. 9:7). The Lord himself said to his disciples: "Believe in God, believe also in me" (Jn 14:1). We can believe in Jesus Christ because he is himself God, the Word made flesh: "No one has ever seen God; the only Son, who is in the bosom of the Father, he has made him known" (Jn 1:18). Because he "has seen the Father", Jesus Christ is the only one who knows him and can reveal him (Jn 6:46; cf. Mt 11:27).   

Reflecting and meditating 

(Youcat comment) At the beginning of faith, there is often an emotional disturbance or uneasiness. The person senses that the visible world and the normal course of things cannot be all there is. He feels touched by a mystery and follows the traces that point to the existence of God and gradually finds the confidence to speak to God and finally to unite himself to him in freedom. In John’s Gospel it says, “No one has ever seen God; the only-begotten Son, who is in the bosom of the Father, he has made him known” (Jn 1:18). That is why we must believe Jesus, the Son of God, if we want to know what God would like to communicate to us. Believing, therefore, means accepting Jesus and staking one’s whole life on him.

(CCC Comment)

(CCC 152) One cannot believe in Jesus Christ without sharing in his Spirit. It is the Holy Spirit who reveals to men who Jesus is. For "no one can say "Jesus is Lord", except by the Holy Spirit" (1 Cor 12:3), who "searches everything, even the depths of God…. No one comprehends the thoughts of God, except the Spirit of God" (1 Cor 2:10-11). 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: Father, Son and Holy Spirit.   

(The next question is: Is there a contradiction between faith and science?)
