Was sickness always caused by sin?
No. Early Christian writings do not treat every sickness as the result of a specific sin. Origen says not every sin is a sickness, and John 9:3 says the blind man or his parents did not sin to cause that blindness. Still, writers like Irenaeus, Cyprian, and Tertullian sometimes link sickness with sin in some cases, especially when reading John 5:14, James 5:15, and 1 Corinthians 11:30.

What did early Christians believe about whether sickness is always caused by sin?
Early Christian teaching is mixed: sickness was sometimes linked to sin, but it was not treated as always caused by sin. Origen says plainly that not every sin is a sickness and does not collapse every illness into personal guilt, while the Gospel of John keeps Jesus from blaming the man born blind or his parents.
At the same time, writers like Irenaeus, Cyprian, and Tertullian sometimes connect illness or weakness with sin, especially when they are reading passages like John 5:14, James 5:15, or 1 Corinthians 11:30. The strongest overall pattern is that early Christians could see some sickness as tied to sin and judgment, but they also knew some sickness had another purpose, such as revealing God’s works or calling for prayer and healing.

The whole man, of course. In fact, since the transgression which caused man's ruin was committed quite as much by the instigation of the soul from concupiscence as by the action of the flesh from actual fruition, it has marked the entire man with the sentence of transgression, and has therefore made him deservedly amenable to perdition.

Tertullian, On Modesty Supporting witness
...s said, "The blood of His Son purifies us utterly from every sin." Then, according to them, we will always sin, and in every form, if He always purifies us utterly from every sin. Or else, if not always, then not again after believing. And if not from sin, then not again from fornication. But what is the point from which John began? He had said that God is Light, and that darkness is not in Him, and that we lie if we say that we have communion with Him and walk in darkness. But if, he says, we walk in the light, we shall have communion with Him, and the blood of Jesus Christ our Lord purifies us utterly from every sin. Then, while walking in the light, do we sin? And if we sin in the light, shall we be utterly purified? By no means. For he who sins is not in the light, but in darkness. So he also shows the way in which we shall be utterly purified from sin: by walking in the light, where sin cannot be committed. Accordingly, when he says that we are utterly purified, the meaning is not that we are purified insofar as we sin, but insofar as we do not sin. For by walking in the light, and not having communion with darkness, we shall act as those who are utterly purified. Sin is no

... that the Lord may strengthen and confirm them. Let us pray for our brothers who are afflicted with sickness, that the Lord may deliver them from every sickness and every disease, and restore them healthy to His holy Church. Let us pray for those who travel by water or by land. Let us pray for those who are in the mines, in banishment, in prisons, and in chains for the name of the Lord. Let us pray for those who are afflicted with bitter slavery. Let us pray for our enemies and those who hate us. Let us pray for those who persecute us for the name of the Lord, that the Lord may calm their anger and scatter their wrath against us. Let us pray for those who are outside and have wandered out of the way, that the Lord may convert them. Let us remember the infants of the Church, that the Lord may perfect them in His fear and bring them to full age. Let us pray for one another, that the Lord may keep and preserve us by His grace to the end, and deliver us from the evil one, and from all the scandals of those who work iniquity, and preserve us for His heavenly kingdom.

... during those hours or days when they go through such things, do they refuse to pray, or to touch a Bible, or to receive the Eucharist? If they admit that they do, then it is plain that they are without the Holy Spirit, who always remains with the faithful. For Solomon says about holy people, "So that each one may prepare himself, so that when he sleeps it may keep him, and when he rises it may speak with him," Proverbs 6:22. For if you think, woman, that when you are in your seven days of separation you are without the Holy Spirit, then if you were to die suddenly, you would depart without the Spirit and without sure hope in God. Or else you must understand that the Spirit is always inseparable from you, since He is not confined to a place. But you need prayer and the Eucharist and the coming of the Holy Spirit, because in this matter you have committed no sin. For neither lawful union, nor childbearing, nor menstrual cleansing, nor a nighttime emission can defile a person's nature or separate the Holy Spirit from him. Nothing can do that except impiety and unlawful conduct. For the Holy Spirit always remains with those who have Him, as long as they are worthy. And when He depa

...ouragement. And if they are seized once more, they may confess and so make amends for their earlier sin. There are also other matters that are required of you, which we have added here as well. If any who have fallen into this temptation begin to be sick, and repent of what they have done, and desire communion, it should by all means be granted to them. Or if you have widows or bedridden people who are unable to support themselves, or those who are in prison or shut out from their own homes, in every case these ought to have someone to care for them. Moreover, catechumens who are taken sick ought not to be neglected, but help should be given to them. And, as a matter of the greatest importance, if the bodies of the martyrs and others are not buried, a serious danger is brought on those whose duty it is to perform this service. Therefore, whoever among you has carried out this duty, and on whatever occasion, we are sure that he is regarded as a good servant, as one who has been faithful in the least and will be appointed ruler over ten cities. May God, however, who gives all things to those who hope in Him, grant that we all may be found in these works. The brothers who are in ch
