Do all you can on your side to strengthen this bond and make it more robust and full of affection, so that it will last for all eternity, remembering the saying of the Romans that with unity and purpose one can achieve everything. Yes, this unity between you will bring success to God's work and nothing but disunion will be able to destroy it. [pp. 84-85]
