An associate of mine objects to the Catholic church because of various teachings. One being that sin is viewed as mortal and venial. Please share the background (history & Biblical support) of the distinction between sin-types and why all sin is not the same.
The questions I have been asked to respond to is:
If God is Holy and therefore will not allow allow sinful beings in his presence, why is not venial sin, just as bad as mortal?
Who made the distinction between types of sin?
Is it not just a “man-made” doctrine? Where is the Biblical support for this?
