The temporal effects of sin affect others not only in natural, but in mystical ways
As far back as the Old Testament, it is made clear that the temporal effects of sin affect others who may not have committed personal sin. The greatest and first example is that of the sin of Adam and Eve which resulted in the fall of man from grace and in his propensity for corruption and personal sin which we call “original sin.”
The Pentateuch (i.e. Torah, the first five Books of the Bible) also speaks of the sins of the fathers being visited upon the children:
Exodus 20:5
“…I am the Lord thy God, mighty, jealous, visiting the iniquity of the fathers upon the children, unto the third and fourth generation of them that hate Me.”
1 Corinthians 12:26 demonstrates that what affects one member of the Body affects another:
“And if one member suffer any thing, all the members suffer with it: or if one member glory, all the members rejoice with it.”
These concepts seem foreign to those who live in the modern Western world’s radically individualistic culture, but they are Scriptural fact. They may seem “unfair” (as though life with our fallen nature is supposed to be fair), but that it is true is obvious by looking at the often sad lives of the poor children of “crack-whores,” or the parents of those who tend to end up in and out of Juvenile Hall, etc. This is not to say that those who suffer the consequences of their ancestors’ sins are doomed! No! All are called to Christ and His Church, and Jesus will judge us as individuals by looking at our hearts, wills, deeds, and intellect, taking into consideration factors which mitigate culpability. Nonetheless, the basic idea that our sins affect others not only in obvious temporal ways, but in mystical ways, is Biblical.
All of these temporal punishments, though painful, are merciful. Without discipline and punishment from God, we would continue in our ways, remain unrepentant, and then suffer the eternal consequences of doing so. A father who does not discipline his children is a bad father who is setting up his child for greater troubles down the road. God, though, is a good Father:
Hebrews 12:5-11
“And have you completely forgotten this word of encouragement that addresses you as a father addresses his son? It says,
‘My son, do not make light of the Lord’s discipline,
and do not lose heart when he rebukes you,
because the Lord disciplines the one He loves,
and he chastens everyone he accepts as His son.’ -Prov. 3:11,12
Endure hardship as discipline; God is treating you as his children. For what children are not disciplined by their father? If you are not disciplined—and everyone undergoes discipline—then you are not legitimate, not true sons and daughters at all. Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of spirits and live! They disciplined us for a little while as they thought best; but God disciplines us for our good, in order that we may share in His holiness. No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it.”

Summa Catechetica, "Neque enim quaero intelligere ut credam, sed credo ut intelligam." – St Anselm, "“Si comprehendus, non est Deus.” -St Augustine, "Let your religion be less of a theory, and more of a love affair." -G.K. Chesterton, “When we pray we speak to God; but when we read, God speaks to us.” -St Jerome, "As the reading of bad books fills the mind with worldly and poisonous sentiments; so, on the other hand, the reading of pious works fills the soul with holy thoughts and good desires." -St. Alphonsus Liguori, "And above all, be on your guard not to want to get anything done by force, because God has given free will to everyone and wants to force no one, but only proposes, invites and counsels." –St. Angela Merici, “Yet such are the pity and compassion of this Lord of ours, so desirous is He that we should seek Him and enjoy His company, that in one way or another He never ceases calling us to Him . . . God here speaks to souls through words uttered by pious people, by sermons or good books, and in many other such ways.” —St. Teresa of Avila, "I want a laity, not arrogant, not rash in speech, not disputatious, but men and women who know their religion, who enter into it, who know just where they stand, who know what they hold and what they do not, and who know their creed so well that they can give an account of it, who know so much of history that they can defend it. I want an intelligent, well-instructed laity… I wish you to enlarge your knowledge, to cultivate your reason, to get an insight into the relation of truth to truth, to learn to view things as they are, to understand how faith and reason stand to each other, what are the bases and principles of Catholicism, and where lie the main inconsistences and absurdities of the Protestant theory.” (St. John Henry Newman, “Duties of Catholics Towards the Protestant View,” Lectures on the Present Position of Catholics in England), "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 . . . What power spiritual reading has to lead to a change of course, and to make even worldly people enter into the way of perfection." –St. Padre Pio, "Screens may grab our attention, but books change our lives!" – Word on Fire, "Reading has made many saints!" -St Josemaría Escrivá, "Do you pray? You speak to the Bridegroom. Do you read? He speaks to you." —St. Jerome, from his Letter 22 to Eustochium, "Encounter, not confrontation; attraction, not promotion; dialogue, not debate." -cf Pope Francis, "God here speaks to souls through…good books“ – St Teresa of Avila, Interior Castle, "You will not see anyone who is really striving after his advancement who is not given to spiritual reading. And as to him who neglects it, the fact will soon be observed by his progress.” -St Athanasius, "To convert someone, go and take them by the hand and guide them." -St Thomas Aquinas, OP. 1 saint ruins ALL the cynicism in Hell & on Earth. “When we pray we talk to God; when we read God talks to us…All spiritual growth comes from reading and reflection.” -St Isidore of Seville, “Also in some meditations today I earnestly asked our Lord to watch over my compositions that they might do me no harm through the enmity or imprudence of any man or my own; that He would have them as His own and employ or not employ them as He should see fit. And this I believe is heard.” -GM Hopkins, SJ, "Only God knows the good that can come about by reading one good Catholic book." — St. John Bosco, "Why don't you try explaining it to them?" – cf St Peter Canisius, SJ, Doctor of the Church, Doctor of the Catechism, "Already I was coming to appreciate that often apologetics consists of offering theological eye glasses of varying prescriptions to an inquirer. 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. Let me ask you this: Would you drink something you knew was poisoned just because it was offered to you in a golden cup?" -St. John Bosco " To teach in order to lead others to faith is the task of every preacher and of each believer." —St. Thomas Aquinas, OP. "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
