Gospel of Matthew 5:28


In Matthew 5:28, it says “But I say to you, everyone who looks at a woman with lust has already committed adultery with her in his heart.”

Does that mean if someone did that, they’d have committed the actual sin of adultery? Or a lesser/different version of it?

Just wanted some clarification on that verse, thanks.

They are both mortal sin, so we should treat them the same. Sure, adultery in the heart only harms the self instead of others, but it is still mortal sin. The actual gravity of the two doesn’t really matter if they are both mortal sins. Of course, the gravity of adultery in the heart can be lessened if it has become a strong habit, but that is up to a priest to decide. If you suffer with this, you should really speak to your priest in confession. Regular confession will return your thoughts to a holy state.

I assume you mean they are both sins of grave matter (not mortal sins). They would only become mortal sins if the person committing them knew they were sins of grave matter.
