The fast of St. Catherine of Siena (d. 1 380) has been recorded for us by none other than one of her confessors, BI. Raymond of Capua. In his biography of St. Catherine he informs us that following a vision of Our Lord, food was no longer necessary to the saint. BI. Raymond writes: "When she was obliged to take food, she was so incommoded that it would not remain in the stomach and it would be quite impossible to describe her grievous pains on such occasions." At the start of her fast, the confessor who served her at the time commanded her to take food daily, but after a time the saint asked him: "If therefore you see, by the numerous experiments of which you have been witness, that I am killing myself by taking nourishment, why do you not forbid me, as you would forbid me to fast, if the fast produced a similar result?"
BI. Raymond tells us that the confessor had nothing to reply to this reasoning and said to her, "Henceforth act according to the inspirations of the Holy Ghost, for I perceive that God is accomplishing marvelous things in you." Sometime later, when her confessor inquired whether she did not at least experience an appetite, the saint replied, "God satisfies me so in the Holy Eucharist that it is impossible for me to desire any species of corporal nourishment." On asking if she did not at least experience hunger on the days on which she did not communicate, the saint answered, "His sole presence satiates me, and I acknowledge that, to be happy, it even suffices for me to see a priest who has just said Mass."
When St. Catherine's fast became well-known many criticized her, and even religious persons were opposed to her. Some attributed the fast to ". . . a kind of vanity, that she did not fast really, but fed herself well in secret." Others said she wished to be noticed and that she was being deceived by the devil. Bl. Raymond writes: "Catherine was willing to appease their murmurs, and determined that every day she would go once and take a seat at the common table and endeavor to eat. Although she used neither meat, nor wine, nor drink, nor eggs, and did not even touch bread. what she took, or rather, what she tried to take, caused her such sufferings that those that saw her, however hard-hearted they were, were moved to compassion; her stomach could digest nothing, and rejected whatever was taken into it; she afterwards suffered the most terrible pains and her whole body appeared to be swollen; she did not swallow the herbs which she chewed, she only drew from them their juice and rejected their substance. She then took pure water to cool her mouth; but every day she was forced to throw up what she had taken, and that with so much difficulty that it was necessary to assist her by every possible means. To this BI. Raymond adds, "As I was frequently witness of this suffering, I felt an extreme compassion for her, and I counselled her to let men talk, and spare herself such torture . ."
"For the seven year period prior to her death, Saint Catherine of Siena took no food into her body other than the Eucharist. Her fasting did not affect her energy, however. She maintained a very active life during those seven years. As a matter of fact, most of her great accomplishments occurred during that period. Her death had nothing to do with malnutrition, or anything connected with lack of food."
Not only did her fasting not cause her to lose energy, but became a source of extraordinary strength, she becoming stronger in the afternoon, after having received our Lord in His Eucharist. One of the only sufferings she found almost intolerable, was to be denied Her Lord in the Eucharist. Neither the Priests at the Basilica of Saint Dominic, nor Catherine's Superior in the Mantellate approved of her receiving the Eucharist daily. They tried to discourage Catherine, unsuccessfully. The Priests flatly refused, insisting she receive solely from her Confessor; it didn't matter if he was out of town. At that time, Catherine would seek comfort looking at the Priest during the Mass. After all, through his consecrated hands, he was bringing her Lord to her on the altar where she could adore Him, even if she could not receive Him. Catherine endured the worst anguish over this until Raymond came to Siena and she was able to receive Communion daily. When he was in town, he would only have to hear her plea, "Father, I hunger," and, if at all possible, he would celebrate Holy Mass.
Pope Gregory XI, who Catherine convinced to return to Rome from Avignon, later decreed a papal bull allowing her to receive daily, her Lord in His "Body and Blood, Soul and Divinity"16, the Eucharist.
Saint Catherine of Siena had Visions during the consecration of the Mass, sometimes seeing Jesus dressed as a Priest, repeating the words He spoke at the Last Supper. Other times, when she gazed upon the raised Host, instead of seeing the Consecrated Host, she saw the Baby Jesus in the Priest's hands. When we hear some people say they do not need Miracles of the Eucharist to believe in the Lord truly Present in the Consecrated Host, I can't help recall Catherine, who was strengthened in her belief in Him when she saw the Host in this miraculous form. She did not need the miracle to believe, but she did not refuse the help it gave her when she needed strength, or maybe as Mother Angelica said, the grace to believe.
Like with Jesus, there are those always putting His chosen ones to the test, possibly, as with Jesus to trick them? One day, a Priest who did not believe in Catherine's Visions and her special relationship with the Eucharist, gave her an unconsecrated host, under the guise it was Holy Communion. Her angry words lashed out at the Priest for trying to cheat and delude someone who hungered for Jesus, in His Body and Blood.
Priests were touched by happenings during Holy Mass with Saint Catherine of Sienna. One reported he saw the Host go to her without him moving his arm. Other Priests said they saw the Host nod to her, almost as if in recognition. There were those who could feel their arms being pulled toward her, with the Host. Raymond of Capua reported he saw a Host travel clear across the church to Catherine. It was as if the Lord desired her as much as she longed for Him. There was a magnet between them and that Magnet was the Eucharist.
At the moment of receiving Communion, her face would become transfixed, as if glorified, surrounded by an aura. Catherine often went into ecstasy at that time, levitating. Her friends remained with her so they could assist her home, as even from childhood, Catherine was always left weakened after an ecstasy.
