No my wifes did not. Mortal sins are serious shit.
ALL sin is 'serious' stuff!
Matthew 5:18-20
18 For amen I say unto you, till heaven and earth pass, one jot, or one tittle shall not pass of the law, till all be fulfilled.
19 He therefore that shall break one of these least commandments, and shall so teach men, shall be called the least in the kingdom of heaven. But he that shall do and teach, he shall be called great in the kingdom of heaven.
20 For I tell you, that unless your justice abound more than that of the scribes and Pharisees, you shall not enter into the kingdom of heaven.
James 4:17 ESV
So whoever knows the right thing to do and fails to do it, for him it is sin.
1 John 1:8-10 ESV
If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say we have not sinned, we make him a liar, and his word is not in us.
Romans 3:23 ESV
For all have sinned and fall short of the glory of God,
Ecclesiastes 7:20 ESV
Surely there is not a righteous man on earth who does good and never sins.
