The sin
141. Sin is a willful offense against God's law.
142. Sin is of two kinds: original and actual.
143. Actual sin is that which we ourselves commit when we come to the use of reason, and can be: mortal and venial.
144. Original sin is that with which we are all born, inherited from our first parents Adam and Eve.
It is erased by Holy Baptism.
(see what was said in question 87, etc.)
145. Mortal sin is to think, desire, say, do or omit something against the law of God in a grave matter.
Sin can be committed by thought, desire, word, deed and omission.
Omission means not to do what one is obliged to do.
Not all sins are the same; as between friends there can arise small and serious displeasures, so it is also between God and man.
Small annoyances do not break the friendship, but serious ones do.
Actual sin can be mortal and venial.
Mortal sin is to break the law of God in a grave matter, with full warning and full consent.
Grave matter, means a thing of importance.
Full warning means that the understanding clearly realizes that the thing is evil.
He does not sin, for lack of warning, who eats meat on a forbidden day, because he does not know or does not remember that it is a day of abstinence.
Full consent means that the will is completely free.
An evil dream, in itself, is not sin, because when one sleeps one is not free to do good or evil.
Where there is no free will, there is no sin.
He does not sin who does something evil unwillingly, compelled by force.
It does not take away the free will to be compelled, but not by force, to do something that otherwise one would not want to do.
One would sin who, because he is threatened with death or some other grave evil, commits an action that is evil in its nature, such as insulting God, abandoning true religion, etc.
For there to be sin, it is not necessary to want to offend God directly.
Only the devil or men similar to the devil can directly want to offend God.
What is intended, in sinning, is only to satisfy one's passion, one's whim.
For there to be sin, it is not even necessary to think that one offends God; it is enough to freely do something illicit, realizing that one should not do it, because it is evil. He who does wrong, without knowing it, through culpable ignorance, sins. He who performs an act, doubting whether it is licit, sins.
He who doubts whether an act is licit or illicit, must first ascertain; and he cannot perform it without knowing that it is licit.
The most practical means of ascertaining whether an act is licit is to ask a confessor.
Whoever does something licit, but mistakenly believes it to be illicit, sins.
Mortal sin is forgiven in two ways:
1º By going to confession
2º By making an act of perfect contrition, with the purpose of going to confession.
146. Grave sin is called mortal because it deprives the soul of the supernatural life of grace.
147. One deserves hell for a single mortal sin.
148. Good works can be done in the state of mortal sin, but without merit for eternal life.
(see what is said in the paragraph entitled “Merit of Good Works”).
149. Venial sin is to think, desire, say, do, or omit something against the law of God in a slight matter.
150. This sin is called venial because it is easily forgiven.
Venial sin is forgiven by repenting of having committed it.
Venial sin defiles the soul and deprives it of many good things, and even disposes it to mortal sin.
God punishes venial sin in this life and in the next.
In this life: Sacred History and Ecclesiastical History tell us of severe punishments inflicted by God on virtuous persons for faults, apparently very slight: little lies, backbiting, negligence in prayer, petty thefts, etc.
In the other life: the fire of Purgatory, similar to that of hell, torments, for a more or less long time, the souls, for slight faults that they have committed during life, for which they have not done sufficient penance.

Sin is the greatest of all evils
We should fear all sin as the greatest of all evils.
Sin is the evil against God, because it takes away the obedience and honor due to Him.
If God were capable of sorrow, sin would cause it. [Jesus Christ, God the Son, is still on the cross because of our sins, so that the Divine Justice of the Father does not destroy us]
Sin, the evil against God, is an infinite evil, because the dignity of the offended God is infinite.
All other evils are evils of the creatures; but all creatures, compared with God, are as nothing: consequently, all their evils are as nothing compared with the evil against God.
Therefore, even to save the whole world from ruin, it would never be licit to commit the least sin.
It can never be lawful to commit a sin, for if it were ever lawful, it would no longer be a sin. [God's law is eternal, what was sin will always be sin. E.g.: it was forbidden to cremate the dead until 1963, now the Church says it can be done. But what prevails is the law of God, which is eternal. Someday the Church will return to the Holy Tradition forever.
It is obvious that with the second coming of Jesus Christ, the Church will be holy again. In the meantime, we cannot be blind sheep.
At the time of St. Athanasius, most of the bishops were Arians, the Pope, it was not sure what he was, those bishops were condemned and the faithful who followed them are also condemned as heretics. Poor those people who thought that the majority is right and that they were safe for following their bishop.
Even if one follows a bishop or an (antipope) like Francis, if those follow modernism, feminism or any other satanism, those who follow those bishops or bad popes will be condemned. Pope Honorius I was condemned after he died.
To follow Holy Tradition or the modernism (Satanism) that came with Vatican Council II? It is obvious that the holier. It is obvious that what the Church followed until 1964 (Our Lady of the Roses tells us not to accept Bibles approved after that year, that is, She took away the bishops' power to approve new versions).
We have the Messages of Our Lady of the Roses to guide us. In OT times, people had to reject the false prophets who were in the majority and choose to follow the true one sent by God. Now it is no different.
If priests were no longer forced to give Communion in the hand as requested by the infiltrated sepulchres (which IS A SACRILEGY according to the Holy Tradition and the Messages of Our Lady of the Roses), if the Messages of Our Lady of the Roses, Mary Help of Mothers were approved and obeyed, we would have hope for peace and joy and good for these times].
Sin is the evil of man: because it takes away eternal happiness, which is his ultimate end.
No other evil causes more fatal consequences.
