Yes - there is not sin that the Church cannot forgive (if there is repentance).
A note about the Seven Deadly Sins from a previous post of mine.
The Seven Deadly sins or perhaps better
Capital sins – can yes involve grave matter for mortal sins. (and of course there are many things that are grave matter…not just seven…I note for some readers)
But that does *not *mean that they (or sins that fall in those categories) are necessarily grave matter.
Many admit rather of parvity of matter (light matter).
And yes I am referring to the matter involved – not just to say a lack of full knowledge or deliberate consent for mortal sin --but to a light matter for venial sin.
The term “deadly” --often confuses persons.
Such is simply not the case that deadly sins/capital sins = grave matter .
For example --the chief of them is Pride. Pride yes can be grave matter --like a person says I do not need God. But often in the life of say a Christian it is venial matter (sinning in pride in other ways…)
Anger can be grave matter – like for example - one is deliberately angry -seeking to say seriously harm someone.
Or seriously wounding charity or justice or the person *deliberately *flies into a rage that it can be said they lost their reason…etc
But often it can be venial in life. One gets a little angry that something did not go the way one wanted…etc
or take gluttony – individual acts of such by way of intemperance are often venial in nature.
Though for example one can have grave matter --for example getting drunk where one looses ones reason…etc.
So no it is not a simple: Deadly sins -Capital sins = grave matter (for mortal sin).
They are called
Capital cause they are the “head” capitus of many other sins that they engender…(and deadly cause yes the seven can be deadly…)
But the term used more so today is
capital sins.
Catechism:
1866 Vices can be classified according to the virtues they oppose, or also be linked to the capital sins which Christian experience has distinguished, following St. John Cassian and St. Gregory the Great. They are called “capital” because they engender other sins, other vices. They are pride, avarice, envy, wrath, lust, gluttony, and sloth or acedia.

- What are vices?
1866-1867
Vices are the opposite of virtues. They are perverse habits which darken the conscience and incline one to evil. The vices can be linked to the seven, so-called, capital sins which are: pride, avarice, envy, anger, lust, gluttony, and sloth or acedia.

Of course sins like fornication, lusting after some woman, adultery etc do not admit of parvity of matter.
