We come to the section in the Catechism that deals with the doctrine of eternal damnation. We see that all sins deserve eternal punishment because they are committed against an infinitely holy and just God. However, we also see that one sin differs from another in its seriousness in God’s sight for a variety of reasons. For example, hatred is less serious than murder, though both are breaches of the 6th Commandment. We see that the Bible teaches there are different degrees of punishment in Hell for sins of different degree.
In all this, as believers we are stirred up to greater thankfulness as we realize that in Christ we have been spared the fires of Hell. Unbelievers, though, are urged to seek salvation in Christ today while it is still the day of salvation.
