37. The Church of the first millennium was born of the blood of the martyrs: "Sanguis martyrum - semen christianorum". The historical events linked to the figure of Constantine the Great could never have ensured the development of the Church as it occurred during the first millennium if it had not been for the seeds sown by the martyrs and the heritage of sanctity which marked the first Christian generations. At the end of the second millennium, the Church has once again become a Church of martyrs. The persecutions of believers —priests, Religious and laity—has caused a great sowing of martyrdom in different parts of the world. The witness to Christ borne even to the shedding of blood has become a common inheritance of Catholics, Orthodox, Anglicans and Protestants, as Pope Paul VI pointed out in his Homily for the Canonization of the Ugandan Martyrs.
This witness must not be forgotten. The Church of the first centuries, although facing considerable organizational difficulties, took care to write down in special martyrologies the witness of the martyrs. These martyrologies have been constantly updated through the centuries, and the register of the saints and the blessed bears the names not only of those who have shed their blood for Christ but also of teachers of the faith, missionaries, confessors, bishops, priests, virgins, married couples, widows and children.
In our own century the martyrs have returned, many of them nameless, "unknown soldiers" as it were of God's great cause.
