Historical records of 12th-century Scandinavia are scanty. Erik existed; he was king; he was a Christian; he is said to have done much to consolidate Christianity in his realm. He led the first Swedish crusade into Finland – an act implicitly confirmed by a Papal bull of the 1170s. He was killed fighting Danish invaders. A chronicle of 1240 says: “The twelfth king was Erik. He was rashly killed in an unhappy moment. He always gave a good example while he lived, and God rewarded him well. Now his soul is at rest with God and his angels, and his bones rest in Uppsala. And he has, with God’s help, made and manifested many precious miracles.”

He was born in Tuscany and elected pope in 523. It was a time of high political and religious tension. Theodoric the Ostrogoth, the ruler of Italy, was an Arian, while many of his subjects were Catholics. Initially tolerant, he became increasingly suspicious of the Catholics’ influence and political allegiance – above all, because they naturally had strong links with the Catholicism of the surviving eastern Roman Empire in Constantinople. Moreover, Arians in the eastern Roman Empire were being persecuted by the Catholic emperor, Justin, and they appealed to Theodoric for help.

Cyril was born in 315 of Christian parents and succeeded Maximus as bishop of Jerusalem in 348. He was active in the Arian controversy and was exiled more than once as a result. His pastoral zeal is especially shown in his Catecheses, in which he expounded orthodox doctrine, holy Scripture and the traditions of the faith. They are still read today, and several of the Second Readings of the Office of Readings are taken from them. He died in 386. He is held in high esteem by both the Catholics and the Orthodox, and he was declared a Doctor of the Church by the Pope in 1883.

Red is the colour of fire and of blood. Liturgically, it is used to celebrate the fire of the Holy Spirit (for instance, at Pentecost) and the blood of the martyrs.
