Must leave the job with occasion of sin

St. Alphonsus, when a lawyer, wrote: "My friend, our profession is too full of difficulties and dangers; we lead an unhappy life and run risk of dying an unhappy death. For myself, I will quit this career, which does not suit me; for I wish to secure the salvation of my soul."
Tannoja, Antonio. "The life of St. Alphonsus Maria de Liguori" (1855) p. 30

From the Sermons of St. Jean-Marie-Baptiste Vianney:

Servants should avoid the growth of too-familiar relationships, which are so dangerous and so fatal to innocence. If you have the misfortune to find yourself in such a situation, you must leave your employment, no matter what it may cost you to do so. Here is an example of those very circumstances wherein you must follow the counsel Jesus Christ gave you when He said that if one's right eye or right hand should be an occasion of sin, one must deprive oneself of them because it is better to go into Heaven lacking an eye or a hand than to be cast into Hell with one's whole body. That is to say, however desirable your position may be, you must leave it at once; otherwise you will never save your soul. Put the salvation of your soul first, our Lord Jesus Christ tells us, because that is the only thing you ought really to have at heart. Alas, my dear brethren, how rare are those Christians who are ready to suffer rather than to jeopardise the salvation of their souls.

• Chapter 6: How to act after an Election

When we have to deliberate, not on the choice of a state of life, but on some undertaking, as, for instance, on accepting or refusing some office, we should keep to the rules laid down in the foregoing chapter, taking care always for this is a capital point to act in view of God's glory and not for earthly interests.^[2]Who does not deplore the sad neglect of this principle in our days ? Passion, human advantages, drive men into careers fraught with danger for salvation, and that for some trifling and perishable gain. Who can tell the amount of evil that flows from such conduct?

As in the time of St. Gregory, so in our own day there are many avocations which a man can scarcely, or even not at all, take upon himself, without committing sin: "Sunt pleraque negotia, quae sine peccatis exhiberi aut vix aut nullatenus possunt" (Hom. 24, in Evang.) Therefore, after his return to God, a man must be exceedingly careful not to expose himself anew to anything that would lead him into sin.
