"In 1879 Catholicism began spreading in Uganda when the White Fathers, a congregation of priests founded by Cardinal Lavigerie were peacefully received by King Mutesa of Uganda.  The priests soon began preparing catechumens for baptism and before long a number of the young pages in the king’s court had become Catholics. However, on the death of Mutesa, his son Mwanga, a corrupt man who ritually engaged in pedophilic practices with the younger pages, took the throne.

When King Mwanga had a visiting Anglican Bishop murdered, his chief page, Joseph Mukasa, a Catholic who went to great length to protect the younger boys from the king’s lust, denounced the king’s actions and was beheaded on November 15, 1885. The 25 year old Charles Lwanga, a man wholly dedicated to the Christian instruction of the younger boys, became the chief page, and just as forcibly protected them from the kings advances.On the night of the martyrdom of Joseph Mukasa, realizing that their own lives were in danger, Lwanga and some of the other pages went to the White Fathers to receive baptism. Another 100 catechumens were baptized in the week following Joseph Mukasa’s death.

The following May, King Mwanga learned that one of the boys was learning catechism. He was furious and ordered all the pages to be questioned to separate the Christians from the others.  The Christians, 15 in all, between the ages of 13 and 25, stepped forward. The King asked them if they were willing to keep their faith. They answered in unison, “Until death!” "

St. Clotilda praying at the foot of Saint Marc's Tomb. Public domain

"The Mission of the Christian Woman: If death has entered the world through the guilt of a woman, woman has, on the other hand, oftentimes been invested with the mission of bringing salvation to the world. It suffices to mention Deborah, Judith, the incomparable Mary, Mother of God; and, coming down to our own times, Genoveva and Clotilda, to the latter of whom France owes Christianity. Being the wife of Clovis, who was a pagan, like the rest of his people, she urged her husband to become a Christian, and each day entreated Heaven to grant his conversion. Heaven came to her assistance. When he was on the point of losing the battle of Tolbiac and his troops had already begun to fly, a sudden thought recurred to the mind of Clovis, and he exclaimed: "God of Clotilda! if Thou givest me the victory, I will become a Christian." God vouchsafed to grant him the victory, and Clovis was true to his word. let not this great boon, however, allow us to forget the other virtues of Clotilda, - her humility, piety, resignation, love for the poor, her austerities, and zeal for religion. She died at Tours in 543, having had a revelation of her death thirty days beforehand, while praying at the tomb of St. Martin. Moral reflection: St. Peter traces out the mission of the Christian woman, "To win the heart of those that believe not the word." (1 Peter 3. 1.). Pictorial half hours with the saints, by Abbe Auguste François Lecanu

Prayer:

Hail, gentle and loving St. Clotilde, sweet illustrious Queen of the Franks, who by thy faith and perseverance in the Lord didst convert thy husband and made France for many centuries a venerable stalwart of the Catholic faith, I implore thy powerful intercession in this my great need. Assist me, holy St. Clotilde, from thy height of glory in heaven. Thou, who during thy earthly sojourn, didst drink deeply from the Saviour's chalice of sorrows, have pity on my dire distress, especially . . . (Here make your intention). Grant also that through my sorrows I may, like thee, purify my faith and never lose hope in the mercy of God. Amen.

May: Month of the Sacred Heart

Virtue: Obedience

Sacred Heart, Brittany

Act of Reparation to the Most Sacred Heart of Jesus

Most Sweet Jesus, whose overflowing charity for men is requited by so much forgetfulness, negligence and contempt, behold us prostrate before Thee, eager to repair by a special act of homage the cruel indifference and injuries to which Thy loving Heart is everywhere subject.

Mindful, alas! that we ourselves have had a share in such great indignities, which we now deplore from the depths of our hearts, we humbly ask Thy pardon and declare our readiness to atone by voluntary expiation, not only for our own personal offenses, but also for the sins of those, who, straying far from the path of salvation, refuse in their obstinate infidelity to follow Thee, their Shepherd and Leader, or, renouncing the promises of their baptism, have cast off the sweet yoke of Thy law.

We are now resolved to expiate each and every deplorable outrage committed against Thee; we are now determined to make amends for the manifold offenses against Christian modesty in unbecoming dress and behavior, for all the foul seductions laid to ensnare the feet of the innocent, for the frequent violations of Sundays and holy days, and the shocking blasphemies uttered against Thee and Thy Saints. We wish also to make amends for the insults to which Thy Vicar on earth and Thy priests are subjected, for the profanation, by conscious neglect or terrible acts of sacrilege, of the very crimes of nations who resist the rights and teaching authority of the Church which Thou hast founded.

Would that we were able to wash away such abominations with our blood. We now offer, in reparation for these violations of Thy divine honor, the satisfaction Thou once made to Thy Eternal Father on the cross and which Thou continuest to renew daily on our altars; we offer it in union with the acts of atonement of Thy Virgin Mother and all the Saints and of the pious faithful on earth; and we sincerely promise to make recompense, as far as we can with the help of Thy grace, for all neglect of Thy great love and for the sins we and others have committed in the past. Henceforth, we will live a life of unswerving faith, of purity of conduct, of perfect observance of the precepts of the Gospel and especially that of charity. We promise to the best of our power to prevent others from offending Thee and to bring as many as possible to follow Thee.

O loving Jesus, through the intercession of the Blessed Virgin Mother, our model in reparation, deign to receive the voluntary offering we make of this act of expiation; and by the crowning gift of perseverance keep us faithful unto death in our duty and the allegiance we owe to Thee, so that we may all one day come to that happy home, where with the Father and the Holy Spirit Thou livest and reignest, God, forever and ever. Amen.
