I just had the hugest spiritual battle of my life, but I fear I may have treaded a little too far into the woods.
It is important to distinguish regarding occasions of sin.
A near occasion for a mortal sin (usually that is the focus of the question): is some thing or person or place etc what generally leads one to commit a particular mortal sin…or likely will cause one to commit the mortal sin in question…
Such can be of a nature that it generally leads most to sin (basically a near occasion for all)…or is particular to a person.
(And that later part yes can change --though we need to take care in judging if something used to be a near occasion --but we think it is not now – it may be important to get some “outside advice” from a confessor.)
Ordinarily we are obliged to avoid such. Though there can be exceptions.
It is not just a temptation per se. Often times one must be around certain temptations due to duty or the simply the society we live in. Etc. (Though there could be say a venial sin by say being tempted and then hesitating with a temptation etc)
(Though we should judge well too what temptations to be around …there are many that it is better to simply avoid entirely and others which one cannot to easily avoid. And there are of course things simply not really fitting for a Christian anyhow.)
And it is not a “remote occasion” where one could be tempted but generally one does not fall. Such are often in our society.
There can also be “necessary” occasions…one can speak with ones confessor in regards to such.
Now of course if something generally does not lead one to mortal sin…but one sees that here and now it will…well one avoids it!
A good confessor too can help one judge.
Compendium issued by Pope Benedict XVI
- When does one commit a mortal sin?
1855-1861
1874
One commits a mortal sin when there are simultaneously present: grave matter, full knowledge, and deliberate consent. This sin destroys charity in us, deprives us of sanctifying grace, and, if unrepented, leads us to the eternal death of hell. It can be forgiven in the ordinary way by means of the sacraments of Baptism and of Penance or Reconciliation.
- When does one commit a venial sin?
1862-1864
1875
One commits a venial sin, which is essentially different from a mortal sin, when the matter involved is less serious or, even if it is grave, when full knowledge or complete consent are absent. Venial sin does not break the covenant with God but it weakens charity and manifests a disordered affection for created goods. It impedes the progress of a soul in the exercise of the virtues and in the practice of moral good. It merits temporal punishment which purifies.
