Aeterna Dei Sapientia §30

³⁰ The Epistles are the letters he wrote as Sovereign Pontiff to the princes, priests, deacons and religious of the universal Church. They display his exceptional qualities of leadership. They show him as a man of keen intellect, yet full of practical good sense; a man of character who kept to his decisions, yet a father most ready to forgive; on fire with charity which St. Paul indicated to all Christians as "a more excellent way."
