Father Josiah addressed this in a long talk on youtube... lying to nazi guards asking about jews hiding etc.. cant remember specifically but along the lines of its OK to lie if not intending to do harmToday at Walmart I was at the self-checkout, almost home free, when a Hispanic man approached me and asked where was my mask. He did not have on a uniform but I saw he was holding a walkie-talkie, suggesting he was a security guard.
I said, "I don't wear one."
"You don't want to or you have a condition?"
"Condition," I replied. Then he left me alone. Problem is I don't have a legitimate condition that prevents me from wearing the mask. I have a condition called being a human being which requires me to breathe in fresh air, but the context in this situation was him asking if I had a medical condition. Therefore I lied to him, which is a sin, and what surprises me is how quickly my corrupted instinct wanted to lie to prevent an escalation in the confrontation that would lead to discomfort. I fought evil with evil. If you have to sin to resist, you should reconsider.
Next time I will say, "No, I don't have a condition" and then deal with the repercussions.
