Here is a post I did before (augmented):
First off there could always be the question – “is such and such a lie?” or is the
matter …the “object” (
scborromeo.org/ccc/p3s1c1a4.htm#1750) in question a different one --where it is simply not “lying”? I leave that to the professional moral theologians to hash out… But such is a real question I would think.
Now…after having said that
–Yes it is a sin to lie…always (see CCC)
But one can use certain licit “mental reservations”…“discreet language”.
Now failing such…
Now lets say one is in the very serious event of the Nazi at the door (or a killer looking for your child)… and one can not find those discreet words…and others lives are at stake …and one thus ends up lying. What then? Well of course one should have found the other way. But in our weakness we sin …indeed we commit venial sins daily …hence they are called at times “daily sins” for which we pray daily “forgive us our trespasses”…and certainly ones culpability will likely be even further reduced by the event of the Nazi’s with the guns at your door…so ones venial sin will be reduced to an even smaller venial sin…which God in his knowing mercy can wipe away as one glances at the Crucifix with prayer after the Nazi’s leave…
God knows that in our seeking to live the varied virtues in our lives we will have venial sins in the process…that we being “saints” …being a new creation in Christ in the state of grace…in charity …living in Christ will still have “daily sins” to pray for. He loves us and continues to purify us with his love. (Not that such is an excuse to not seek to overcome our sins more and more in our lives …nor ought we seek or plan to lie in this case …but rather seek to find the right way. It is just that in the world where various kinds of virtues must be lived in difficult circumstances -we are not always going to find the right way to do so to live each one at that moment as we ought-- we will commit venial sins unfortunately)
Other examples could also be given …
Now all this* does not* make it “good” to lie. Or not a sin to lie. Nor does the ends in this circumstance “justify” the means of the lie.
It remains a lie. A sin.
But so too does the intemperance that one exhibited that morning at breakfast with too many eggs or the little anger one expressed at ones spouse that afternoon. If one falls here too…it will be another venial sin. Another weakness. I am not saying it is “ok” to thus lie or “hey it is only a venial sin in various cases” or encouraging anyone to lie etc. It is something that ought not have happened. One ought to have found a good way.
But it is somewhat understandable that it may happen in such events of Nazi’s at the door… even to Christians. To saints.
And there is really no point in trying to argue too much about such….
