Keep unity and peace to be heard and to inherit
The imprisoned letter writers interrupt their prison report to urge their brothers to keep unity, love and peace.
Now, dearest brothers, something must also be said about the love we have for one another. We are not instructing you but reminding you, for as we were of one mind together, so we also live as one before the Lord and pray as one. The unity of love must be held fast, and we must cling to the bonds of love. Then the devil is thrown to the ground, and then whatever we ask is received from the Lord, for he himself promises and says, "If two of you agree on earth about anything you ask from my Father, it will be yours" (Matthew 18:19).
Nor can we receive eternal life and reign with Christ in any other way, unless we do what he commanded to be done, he who promised both life and the kingdom. The Lord himself declares by his own teaching that those who have kept peace with their brothers attain the inheritance of God, when he says, "Blessed are the peacemakers, for they will be called children of God" (Matthew 5:9). The apostle explains this when he says, "We are children of God, and if children, then heirs: heirs of God and fellow heirs with Christ, if we suffer with him, so that we may also be glorified together with him" (Romans 8:16-17).
So if no one can be an heir except as a child, and no one is a child except as a peacemaker, whoever breaks the peace of God will not be able to hold the inheritance of God. And we do not say this as people who have not been warned, nor do we urge it without a divine showing.

X. Iam nunc, dilectissimi fratres, et de amore quem in nos invicem habemus aliqua dicenda sunt. nec instruimus, sed admonemus quia, sicut simul unanimes fuimus, ita et apud dominum una vivimus et oramus. tenenda est concordia caritatis, dilectionis vinculis inhaerendum est. tunc diabolus prosternitur, tunc a domino quicquid postulatur accipitur, ipso pollicente ac dicente: Si duo ex vobis convenerint super terram de omni re quamcumque petieritis a patre meo, continget vobis. nec alio modo vitam aeternam accipere et cum Christo regnare poterimus, nisi fecerimus quod praecipit faciendum, qui et vitam promisit et regnum. eos denique hereditatem dei consequi, qui pacem cum fratribus tenuerint, suo magisterio ipse dominus denuntiat dicens: Beati pacifici, quoniam filii dei vocabuntur. quod exponens apostolus ait: Sumus filii dei. si autem filii, et heredes; heredes quidem dei, coheredes autem Christi, siquidem compatiamur, ut et commagnificemur. si heres esse non potest nisi filius, filius autem non est nisi pacificus, hereditatem dei habere non poterit qui pacem dei rumpit. et hoc non quasi (non) admoniti dicimus aut sine divina ostensione suggerimus.
