new rules on sin?

[traillius]

Hello,
Can someone tell where I can find info on what constitutes a mortal sin, I think the ‘rules’ may have changed. I know 10 commandments are the basic guidelines. I am just not sure what exactly is included.

In order for a sin to be mortal, it must meet three conditions:

Mortal sin is a sin of grave matter
Mortal sin is committed with full knowledge of the sinner
Mortal sin is committed with deliberate consent of the sinner
This means that mortal sins cannot be done “accidentally.” A person who commits a mortal sin is one who knows that their sin is wrong, but still deliberately commits the sin anyway. This means that mortal sins are “premeditated” by the sinner and thus are truly a rejection of God’s law and love.
"The first condition, that a mortal sin is of grave matter, means that certain premeditated offenses against God are more severe than others. We know that some sins are graver than others (e.g. it is a graver sin to murder someone than to lie to someone). St. John tells us, "If anyone sees his brother sinning, if the sin is not deadly, he should pray to God and he will give him life. This is only for those whose sin is not deadly. There is such a thing as deadly sin, about which I do not say that you should pray. All wrongdoing is sin, but there is sin that is not deadly." (1 John 5:16-17). Thus St. John distinguishes between mortal and venial sin. Jesus also warns us that "Anyone who does not remain in me will be thrown out like a branch and wither; people will gather them and throw them into a fire and they will be burned" (John 15:6)."

Forgiveall is right on what constitutes a mortal sin.

If you’re looking for a list of specific sins, here’s an Examination of Conscience that you might find helpful. I use it myself to prepare for Confession.
