I was talking to my brother (who is southern Baptist) about religious matters. I mentioned mortal and venial sin and he said that he thinks there’s only one kind of sin. Can someone explain in detail what is venial and mortal sin and where do we get the separation from?
If he believes in “once saved always saved” then he may not even think that sin is important since he is already saved. This also explains why Baptists don’t believe that baptism is necessary because baptism washes away sin. But they are saved when they take Jesus as their personal Lord and savior. They may baptize someone, but it is only because it is an ordinance, that is, Jesus requested it to be done. They may also baptize someone when they want to make them a member of a local church. But it is just a ceremony and doesn’t have any connection to sin.
The reason they pray for sinners is primarily for those who have not yet accepted Jesus. But once that person has accepted Jesus, then their prayers stop for them since they are now saved once and for all. They might pray for other good things, but not over sin.
So to explain mortal and venial sin really doesn’t mean anything to them as they are saved and sin can’t touch them whether mortal or venial. If I believed in that I wouldn’t be interested either.
To reach them on this, it seems to me that the real meaning of baptism needs to be explained, that of water washing a person clean of all sin and saving them, but that it doesn’t mean they can’t lose their cleanliness and holiness by sin. And not every sin will take away their holiness, but just serious/mortal sin, and that is why it is called mortal sin and not venial sin.
Now there are verses in the bible that refer to mortal sin, one verse in particular refers to it by name. There are other verses that St. Paul wrote which state that if a person does these sins, such as adultery, murder, etc., they will not enter the kingdom of heaven. Which right there is saying that “once saved always saved” is a false hope. He says this in several different verses.
And so we catholics have a way of forgiveness if we commit serious sins after baptism which is in agreement of what the bible teaches.
Now you may not experience any reaction if you explain these things to him, but then that isn’t your responsibility but the Holy Spirit’s. You plant the seed, an idea, and let the Holy Spirit bring it to goodness.
May God bless and keep you. May God’s face shine on you. May God be kind to you and give you peace.
