In 1John 5: 16, “sin which is deadly” refers not to sin that causes physical death, but to sin that leads to spiritual death. Catholics understand what this verse is referring to - mortal (deadly) and venial (not deadly) sins. Examples of mortal sins are murder, adultery, abortion - sins that, if left unforgiven (see John 20:21-23, 1John 1:9), will land the sinner in Hell, which is spiritual death.Um no your missing the point
if I go get drunk and get into a vehicle and drive and get killed in the process. I have com tied a deadly sin (physical death)
if I say a white lie, or get drunk or commit any other sin, according to the law of God, I deserve spiritual death (the penalty of sin is death). Hence I better received the gift of God, or I will suffer what I deserve, death.
your church does not comprehend this biblical fact, that’s why I An not accept your church
There are lesser sins that don’t deserve the same punishment as mortal sins and won’t land the sinner in Hell if left unforgiven - for example, stealing a pen from your place of employment doesn’t deserve the same punishment as murdering someone.
Now getting back to my original point … one cannot understand what 1John 5:16-17 means if one relies solely on the Scriptures. Only through Church teaching can one make sense of this passage.
