Lk 7: 18b-23
The disciples of John told him about all these things. John summoned two of his disciples
and sent them to the Lord to ask, “Are you the one who is to come, or should we look for another?”
When the men came to him, they said, “John the Baptist has sent us to you to ask, ‘Are you the one who is to come, or should we look for another?'”
At that time he cured many of their diseases, sufferings, and evil spirits; he also granted sight to many who were blind.
And he said to them in reply, “Go and tell John what you have seen and heard: the blind regain their sight, the lame walk, lepers are cleansed, the deaf hear, the dead are raised, the poor have the good news proclaimed to them.
And blessed is the one who takes no offense at me.”

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.
Saint John of the Cross
Saint John of the Cross (Spanish: San Juan de la Cruz; 1542 – 14 December 1591) was a major figure of the Counter-Reformation, a Spanish mystic, a Roman Catholic saint, a Carmelite friar and a priest who was born at Fontiveros, Old Castile.
John of the Cross was a reformer in the Carmelite Order of his time and the movement he helped initiate, along with Saint Teresa of Ávila, eventually led to the establishment of the Discalced Carmelites, though neither he nor Teresa were alive when the two orders separated. He is also known for his writings. Both his poetry and his studies on the growth of the soul are considered the summit of mystical Spanish literature and one of the peaks of all Spanish literature. He was canonized as a saint in 1726 by Pope Benedict XIII. He is one of the thirty-six Doctors of the Church.
