We bow before the martyrdom of those who, at the cost of their own lives, have given witness to the truth of the Gospel, preferring death to the denial of Christ. We believe that these martyrs of our times, who belong to various Churches but who are united by their shared suffering, are a pledge of the unity of Christians. It is to you who suffer for Christ’s sake that the word of the Apostle is directed: “Beloved … rejoice to the extent that you share in the sufferings of Christ, so that when his glory is revealed you may also rejoice exultantly” (1 Pet 4:12–13).
