PenitentMan,
My brother, I’m not sure that you’re doing this, but Iet me gently caution you to avoid becoming legalistic in your quest to determine whether or not drunkenness is a mortal sin.
The Catechism, in explaining mortal and venial sin, says “venial sin does not deprive the sinner of sanctifying grace, friendship with God, charity, and consequently eternal happiness.” (
CCC 1863) However, Galatians 5:21 explains that those who engage in drunkenness “shall not obtain the kingdom of God.” If venial sin does not deprive the sinner of eternal happiness, then Galatians 5:21 would establish that drunkenness is not a venial sin because it leads to banishment from eternal life with God: it’s a mortal sin.
The point is, though, that drunkenness
is sinful. If it’s “only” a venial sin, does that mean you can go ahead and do it? Our faith in God is what guides us. That faith is not a legal system with regulations and subsections. We should not act as though we are lawyers trying to discover loopholes that allow us worldly pleasures or avoid legal traps that might land us in the can. We are called to live a live of faith. The Pharisees tried to trap Jesus in their legal system:
Matthew 12:10-12
10 And behold there was a man who had a withered hand, and they asked him, saying: Is it lawful to heal on the sabbath days? that they might accuse him.
11 But he said to them: What man shall there be among you, that hath one sheep: and if the same fall into a pit on the sabbath day, will he not take hold on it and lift it up?
12 How much better is a man than a sheep? Therefore it is lawful to do a good deed on the sabbath days.
We should not be the Pharisees of today. We should place our faith in God and in His Word and live according to it.
