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. As far as possible, their witness should not be lost to the Church. ... The local Churches should do everything possible to ensure that the memory of those who have suffered martyrdom should be safeguarded, gathering the necessary documentation. This gesture cannot fail to have an ecumenical character and expression.
Perhaps the most convincing form of ecumenism is the ecumenism of the saints and of the martyrs. The communio sanctorum speaks louder than the things which divide us. The martyrologium of the first centuries was the basis of the veneration of the Saints. By proclaiming and venerating the holiness of her sons and daughters, the Church gave supreme honour to God himself; in the martyrs she venerated Christ, who was at the origin of their martyrdom and of their holiness.
In later times there developed the practice of canonization, a practice which still continues in the Catholic Church and in the Orthodox Churches. In recent years the number of canonizations and beatifications has increased. These show the vitality of the local Churches, which are much more numerous today than in the first centuries and in the first millennium.
The greatest homage which all the Churches can give to Christ on the threshold of the third millennium will be to manifest the Redeemer's all-powerful presence through the fruits of faith, hope and charity present in men and women of many different tongues and races who have followed Christ in the various forms of the Christian vocation.
