It was perilous in the extreme to their eternal salvation for Catholics to live as slaves in Muslim society because of their grossly immoral customs. Women were in special danger because they were habitually sold into Muslim harems.
Novena to Our Lady of Good Remedy
But God did not leave His people unaided. He inspired several religious institutions to work towards the rescue of the Catholic slaves from their Muslim slave masters.
One of these was the Trinitarian Order, which was founded by Saint John Matha in 1198. This Order was founded to redeem Catholic slaves from the Islamic slave markets and to set them free.
However, only by raising large sums of money could the Trinitarians carry out their mission of buying back Catholic slaves. To be successful in raising such huge sums of money, they confided their fundraising efforts to the merciful protection of the Blessed Virgin Mary.
And She did not let them down. In fact, the Mother of God was so generous in answering their pleas for funds, that they called Her "Our Lady of Good Remedy."
And so, the Trinitarians were able to free many slaves from the bondage of slavery and, above all, to free them from the moral evils of sin that was prevalent in those decadent Muslim societies.
