Eph 5, 5 No immoral person has inheritance

(Eph 5, 5) No immoral person has inheritance

[5] Be sure of this, that no immoral or impure or greedy person, that is, an idolater, has any inheritance in the kingdom of Christ and of God.

(CCC 1855) Mortal sin destroys charity in the heart of man by a grave violation of God's law; it turns man away from God, who is his ultimate end and his beatitude, by preferring an inferior good to him. Venial sin allows charity to subsist, even though it offends and wounds it. (CCC 1856) Mortal sin, by attacking the vital principle within us - that is, charity - necessitates a new initiative of God's mercy and a conversion of heart which is normally accomplished within the setting of the sacrament of reconciliation: When the will sets itself upon something that is of its nature incompatible with the charity that orients man toward his ultimate end, then the sin is mortal by its very object… whether it contradicts the love of God, such as blasphemy or perjury, or the love of neighbor, such as homicide or adultery.... But when the sinner's will is set upon something that of its nature involves a disorder, but is not opposed to the love of God and neighbor, such as thoughtless chatter or immoderate laughter and the like, such sins are venial (St. Thomas Aquinas, STh I-II, 88, 2, corp. art.). (CCC 1857) For a sin to be mortal, three conditions must together be met: "Mortal sin is sin whose object is grave matter and which is also committed with full knowledge and deliberate consent" (RP 17 § 12).
