[Sidenote: Abuses in the Church to be corrected] Now in the synod held at the apostolic seat to which the divine will has called us (at which some of your subjects also were present) we, seeing that the Christian religion had been weakened by many attacks and that the chief and proper motive, that of saving souls, had for a long time been neglected and slighted, were alarmed at the evident danger of the destruction of the flock of the Lord, and had recourse to the decrees and the doctrine of the holy fathers. We decreed nothing new, nothing of our invention; but we decided that the error should be abandoned and the single primitive rule of ecclesiastical discipline and the familiar way of the saints should be again sought out and followed.[386] For we know that no other door to salvation and eternal life lies open to the sheep of Christ than that which was pointed out by Him who said: "I am the door: by me if any man enter in he shall be saved, and find pasture" [John, x. 9]; and this, we learn from the gospels and from the sacred writings, was preached by the apostles and observed by the holy fathers. And we have decided that this decree--which some, placing human above divine honor, have called an unendurable weight and an immense burden, but which we call by its proper name, that is, the truth and light necessary to salvation--is to be received and observed not only by you and your subjects, but also by all princes and peoples of the earth who confess and worship Christ; for it is greatly desired by us, and would be most fitting to you, that as you are greater than others in glory, in honor, and in virtue, so you should be more distinguished in devotion to Christ. [Sidenote: Gregory disposed to treat Henry fairly] Nevertheless, that this decree may not seem to you beyond measure grievous and unjust, we have commanded you by your faithful ambassadors to send to us the wisest and most pious men whom you can find in your kingdom, so that if they can show or instruct us in any way how we can temper the sentence promulgated by the holy fathers without offense to the eternal King or danger to our souls, we may consider their advice. But, even if we had not warned you in so friendly a manner, it would have been only right on your part, before you violated the apostolic decrees, to ask justice of us in a reasonable manner in any matter in which we had injured or affected your honor. But from what you have since done and decreed it is evident how little you care for our warnings, or for the observance of justice. [Sidenote: Henry's obligation to serve and obey the papacy]
