6 To embrace religion is a most serious duty, which is nor to be restricted by age. No age is unfit for the kingdom of God. As everyone knows this, so he ought to act without delay, for from the will to act is born the right to act for everyone, which cannot be violated without the greatest injury. Therefore, if pastors of souls are forced to make a choice in the matter, they must choose to endure the penalties prescribed by civil law rather than provoke the wrath of an avenging God.
