St Camillus led the life of a typical rebellious teenager. Even following the ways of what were street gangs of that time. It wasn't until later in life, while repairing a monastary as a mason's assistant, that he converted and repented for sins due to the influence of the Capuchin Fathers. He later joined the monastary but was dismissed due to repeated leaves of absence because of recurring leg problems. He spent the rest of his life caring for the sick.
The origin of the Red Cross symbol we are so familiar with today is the symbol his mother saw him wearing in her dreams. It became the symbol for the Order of Ministers of the Sick which was founded by Saint Camillus in 1586.
Most merciful Father, in many ways you have shown your love and care to your people, especially to the poor and the sick. Because your servant St. Camillus has shown your compassion in an admirable manner, you have welcomed him among your saints. We graciously put in St. Camillus’ hands ourselves and our loved ones, and through his intercession we beg you to grant us your abundant graces through Jesus Christ, our Lord. Amen.
