If you ever find yourself on the Holy Mountain or in other old churches, you will notice that many of them are painted red. If you ask the monks, they will tell you that the colour symbolizes the blood of Christ and His saints. It wants to remind us that, whereas the various religions or ideologies spread via propaganda, violence or oppression, the Church of Christ won people’s hearts through weakness, the blood of Christ and the saints, martyrdom and witness. There is not a single Orthodox Church that has not experienced its own martyrdom. And nor is there a saint that has not passed through his or her furnace of sorrows, temptations or martyrdom.
