Five Biblical Lists of Mortal Sins

The first reading for Wednesday of the 27th Week of the Year, from Galatians, spoke to sins that exclude one from the Kingdom of Heaven. If one dies unrepentant from committing any of these sins, one cannot go to Heaven but rather must be excluded in Hell. It is an important reminder to pay heed to the toll that sin takes on our heart, our character, and ultimately our destiny.

One of the great deceptions of our time is that serious sin is only a remote possibility for most people and that such sins are only committed by truly wicked people. Too many people assess their moral standing with unhelpful platitudes such as these: “I’m basically a good person,” or “Well, I haven’t murdered anybody.”

We must be more serious and mature in our discernment. Of course, God does not leave us in such a fog of uncertainty. His Word is quite clear in specifying some of the more serious sins so that we can humbly recognize our tendency to do these very things. Note that stating that a particular sin excludes one from the Kingdom of Heaven is the biblical way of saying that it is a mortal sin.

Simply listing mortal sins is not sufficient because there are important factors affecting culpability. For example, some of the sins listed below (e.g., lying) can admit of lighter matter (one might tell a lie to avoid hurting someone’s feeling). Lies can also be devastating, robbing people of their good name or depriving people of necessary information. Some of the sins listed can result from a compulsions or addictions that erode the freedom necessary to be guilty of mortal sin. Hence, a sin that is of itself serious in nature might be venial if the person were acting under some compulsion. This does not mean that it is not a sin at all, just that it may not be fully mortal in its effects.

Nevertheless, the Lord, in love, wants to warn us urgently of the sins that exclude us from Heaven. In reading from the lists that follow, avoid adopting a legalistic mentality. Take them to heart and allow them to become part of your daily moral reflection. The Lord warns us in love that sin is a serious matter. Even smaller sins, unattended to, begin to grow like a cancer and can ultimately kill us spiritually.

Rather than continue with a lot of commentary, I’d like to post five biblical lists of the more serious sins that exclude one from the Kingdom of God.

Be serious about them. Do not buy into the deception that sin is a trivial matter. God loves us, and because He loves us He warns us that unrepentant sin is serious and can rob our hearts of the desire for Him, for Heaven, and for the good things awaiting us there.

Here, then, are five lists. They are not exhaustive and there are other passages in the Bible that include sins not mentioned below (e.g., refusal to forgive, cf Matt 6:15).

  • Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor homosexual offenders, nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. And that is what some of you were (1 Cor 6:9-10).
  • The acts of the flesh are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God (Gal 5:19-21).
  • But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God’s holy people. Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving. For of this you can be sure: No sexually immoral, impure or greedy person—such a person is an idolater—has any inheritance in the kingdom of Christ and of God. Let no one deceive you with empty words, for because of such things God’s wrath comes on those who are disobedient. Therefore, do not be partners with them (Eph 5:3-6).
  • “Look, I am coming soon! My reward is with me, and I will give to each person according to what they have done. I am the Alpha and the Omega, the First and the Last, the Beginning and the End.” Blessed are those who wash their robes, that they may have the right to the tree of life and may go through the gates into the city. Outside are the dogs, those who practice magic arts, the sexually immoral, the murderers, the idolaters and everyone who loves and practices falsehood. “I, Jesus, have sent my angel to give you this testimony for the churches. I am the Root and the Offspring of David, and the bright Morning Star” (Rev. 22:12-16).
  • Then he will say to those on his left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels. For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me.’ They also will answer, ‘Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?’ He will reply, ‘Truly I tell you, whatever you did not do for one of the least of these, you did not do for me.’ Then they will go away to eternal punishment, but the righteous to eternal life (Matt 25:41-46).

Finally, here is a general warning from the Lord:

Do not be amazed at this, for a time is coming when all who are in their graves will hear his voice and come out—those who have done what is good will rise to live, and those who have done what is evil will rise to be condemned. By myself I can do nothing; I judge only as I hear, and my judgment is just, for I seek not to please myself but him who sent me (John 5:28-29).

Here is a performance of Gregorio Allegri’s “Miserere Mei” (Psalm 51). “Have mercy on me, O God, according to thy great kindness.”

  1. After reading the Seder post from 2012, I have been looking for more information on the possibility of Mary being present at the Last Supper. Did the ancient Seder meal have the mother figure leading the meal, or did the addition come later?
    Sorry for changing the topic, but I really did want to know!
    Many thanks,

  2. The list of mortal sins that I often refer to is Revelation 21:8

    But as for the cowardly, the faithless, the polluted, as for murderers, fornicators, sorcerers, idolaters, and all liars, their lot shall be in the lake that burns with fire and brimstone, which is the second death.

    What always catches my attention is that the cowardly is listed right at the top. I think about what that could mean, especially in my own life.

    Thanks for the blog. It means a lot to me and my family. We read it everyday.

  3. Msgr Pope: We always look forward to reading your Articles. Lately, however, your Articles (including this one), don’t directly address the sins of the Shepherds, who have led many astray. It seems to us, damnation doesn’t bother or concern them. They, like Martin Luther, want Holy Scripture re-interpreted, with respect to; adultry, abortion, homosexuality, contraception, divorce, etc., AND, the chief shepherd is doing and saying nothing. MSGR POPE, WHEN WILL THE GARBAGE BE TAKEN OUT OF OUR CHURCH? We are Cradle Catholics, have been married for 50+ years, and would like to see this done before we leave this earth. What do you say?

    1. I’m surprised you’d say this. I’ve seen that Msgr. Pope has actually written about this many times here and elsewhere — including the blog post for today (Thursday).

      As for when the garbage will be taken out, Jesus says it will happen at “the harvest,” i.e. the end of time (Matthew 13:29-30). Until then, we will suffer sin in the Church on earth.

  4. To be morally good or morally bad depands on one initiative and effort. As we all know God is calling all the time and we is needed of us is to respond to his calling positively so as to rescue our soul and spirit. We are free to do that because He created us and gave us freedom of choice called foundmental option and free will. If a person wants to save his life he or she has to a true child of God his father who is Love and Mercy.

  5. I would need to see what is meant by “fundamental option”. There is a kind it of which claims that no one can mortally sin unless they formally declare before committing a gravely wrong act that they intend to break their relationship with God. This is of course wildly incorrect and soundly refuted by Cardinal Arinze. Do a search on Youtube for Arinze and fundamental option.

  6. Like many others, i look forward to His coming, but i know I am a great sinner and in need of healing. It is a terrible thing to fall into the Judgement of God, and who wants anyone to go to Hell for sin, so thank God for His patience and spend time growing your Love for God and fellow sinners. Just my opinion.
