Saints of the Old Testament: St. Daniel, prophet

While the Roman Church's traditional calendar of saints on this day bestows chief honor upon the holy virgin Praxedes, next in order after St. Praxedes the traditional Roman Martyrology also recalls her children's memory to an Old Testament saint who was blessed with the singular grace of seeing remarkably detailed visions and uttering astoundingly precise predictions of the course of the history of Israel, the Church, and the world:

This Day, the Twenty-First Day of July

At Rome, the holy virgin Praxedes, who was brought up in all chastity and in the knowledge of the divine law. Assiduously attending to watching, prayer and fasting, she rested in Christ, and was buried near her sister Pudentiana, on the Salarian road. 

At Babylon, the holy prophet Daniel.

St. Daniel, whose name in Hebrew means "God is my judge," was a heroically virtuous young Jewish man whom the Babylonians carried away from Jerusalem into captivity in 605-604 B.C.

Saints of the Old Testament: Sts. Ananias, Azarias and Misael

While the Church Universal today commemorates the heavenly birthday of St. Eusebius of Vercelli, bishop and martyr, she also recalls the exemplary holiness of three Old Testament saints, whose names are enrolled in the traditional Roman Martyrology immediately following that of St. Eusebius:

This Day, the Sixteenth Day of December

St. Eusebius, bishop of Vercelli and martyr, mentioned on the 1st of August, and also on the 15th of this month. 

The young men, Ananias, Azarias and Misael, whose bodies were buried in a cavern at Babylon.
