YOUCAT Question n. 90 - Did Jesus work miracles, or are they just pious tales?

(Youcat answer) Jesus really worked miracles, and so did the Apostles. The New Testament authors refer to real incidents.      

A deepening through CCC

(CCC 547) Jesus accompanies his words with many "mighty works and wonders and signs", which manifest that the kingdom is present in him and attest that he was the promised Messiah (Acts 2:22; cf. Lk 7:18-23).      

Reflecting and meditating 

(Youcat comment) Even the oldest sources tell of numerous miracles, even the raising of the dead, as a confirmation of Jesus’ preaching: “But if it is by the Spirit of God that I cast out demons, then the kingdom of God has come upon you” (Mt 12:28). The miracles took place in public; some of the persons involved were known by name, for instance, blind Bartimaeus (Mk 10:46-52) or Peter’s mother-in-law (Mt 8:14-15). There were also miracles that in those Jewish circles were considered shocking and outrageous (for example, the cure of a crippled man on the sabbath, the cure of lepers). Nevertheless they were not disputed by contemporary Judaism.

(CCC Comment)

(CCC 548) The signs worked by Jesus attest that the Father has sent him. They invite belief in him (cf. Jn 5:36; 10:25, 38). To those who turn to him in faith, he grants what they ask (Cf. Mk 5:25-34; 10:52; etc.). So miracles strengthen faith in the One who does his Father's works; they bear witness that he is the Son of God (Cf. Jn 10:31-38). But his miracles can also be occasions for "offense" (Mt 11:6); they are not intended to satisfy people's curiosity or desire for magic Despite his evident miracles some people reject Jesus; he is even accused of acting by the power of demons (Cf. Jn 11:47-48; Mk 3:22).      

(The next question is: But why did Jesus work miracles?)
