“The Gospel describes both justice and the interior dispositions that go even further in making one righteous. The cardinal virtue of justice, as St. Thomas Aquinas defines it, is the “habit whereby a man renders to each one his due by a constant and perpetual will.”
From this, we can draw out two of the chief characteristics of justice. The first is that it is concerned with other persons. It’s about giving to one distinct from oneself what he or she deserves. Secondly, justice is objective. It is primarily about the thing that is owed. It is not about what the other wants to receive or what you want to give.
The commandment “Thou shalt not kill” regards justice, then, in its most proper form. It is a matter of showing due respect for the life God has given to the other man. Jesus gives other examples of unjust behavior to avoid. One owes respect not just to the life of the other but to his dignity as man as well, and so one ought not to disdain him by slandering or committing detraction against him. Christ goes even further than justice properly speaking (i.e., our outward actions) and addresses what can be called justice analogously. That is, He describes how to “be right” with oneself, and this is by overcoming one’s passions, such as anger.
If the Gospel passage talks about establishing a just relation with our brother, what about our relationship with God? We might be tempted to think that Lent is about merely establishing a just relationship between ourselves and Him. Perhaps, for example, we think of the penances we undertake simply as a way of “repaying” God for dying on the Cross for us. It does indeed fall within the scope of justice to offer prayers and sacrifices to God, since we owe all we have and even our very existence to Him. We can never really repay God fully, though, either for that existence or for the redemption He worked for us. So we can never have a truly just relationship with Him in that sense.
Lent is not about evening things out with God. Since our prayers and sacrifices add nothing to God’s greatness or happiness, they are not primarily for His benefit, but rather for our own. Lent helps us recognize what we owe God, but even beyond that it is about preparing for the celebration of Christ’s supreme act of charity in suffering His Passion and death for our salvation. The prayer and penances are a means to our growth in charity, which is achieved when obstacles between ourselves and God are removed.
As Jesus notes in the Gospel, one of those obstacles often is a lack of peace with our brother. For, “he who does not love his brother whom he has seen, cannot love God whom he has not seen” (1 Jn 4:20). This Lent, may the charity of the Just Man fill us with longing for the kingdom of heaven and inspire us to imitate Him.”

Orat., "We cannot always have access to a spiritual Father for counsel in our actions and in our doubts, but reading will abundantly supply his place by giving us directions to escape the illusions of the devil and of our own self-love, and at the same time to submit to the divine will.” —St. Alphonsus Ligouri, "The harm that comes to souls from the lack of reading holy books makes me shudder . . .

Only one prescription will give him clear sight; all the others will give him at best indistinct sight. What you want him to see—some particular truth of the Faith—will remain fuzzy to him until you come across theological eye glasses that precisely compensate for his particular defect of vision." -Karl Keating, "The more perfectly we know God, the more perfectly we love Him." -St Thomas Aquinas, OP, ST, I-II,67,6 ad 3, “But always when I was without a book, my soul would at once become disturbed, and my thoughts wandered." —St. Teresa of Avila, "Let those who think I have said too little and those who think I have said too much, forgive me; and let those who think I have said just enough thank God with me." –St. Augustine, "Without good books and spiritual reading, it will be morally impossible to save our souls." —St. Alphonsus Liguori "Never read books you aren't sure about. . . even supposing that these bad books are very well written from a literary point of view.

"Prayer purifies us, reading instructs us. Both are good when both are possible. Otherwise, prayer is better than reading." –St. Isidore of Seville “The aid of spiritual books is for you a necessity.… You, who are in the midst of battle, must protect yourself with the buckler of holy thoughts drawn from good books.” -St. John Chrysostom
