Letter sent by Blessed Gregory X to Blessed John of Vercelli, Master General of the Order of Preachers
Gregory, Bishop, Servant of the Servants of God, to our very dear son, the Master General of the Order of Preachers, salutation and apostolic benediction.
Recently, during the Council held at Lyons, we deemed it a useful commendation to exhort the faithful to enter the house of God with humility and devotion, and to conduct themselves while there in a becoming manner, so as to merit the divine favour and at the same time to give edification. We have also judged it proper to persuade the faithful to demonstrate more reverence for that name above all names, the only name in which we claim salvation- the name of Jesus Christ, Who has redeemed us from the bondage of sin. Consequently, in view of obeying that apostolic precept, in the Name of Jesus let every knee be bent; we wish that at the Holy Sacrifice, every one would bow his head in token that interiorly he bends the knee of his heart.
Wherefore, my very dear son, we, by our apostolic authority, exhort and enjoin upon you and the brothers of your Order to use solid reason in preaching to the people, that they may be led to comply with our desires. Thus you will win the crown of justice in the day of recompense.
Given at Lyons, on the twelfth Calendes of October, third year of our Pontificate.
