I’m sorry but you’re one short. There are three conditions for mortal sin. One, grave matter. We all agree on that one. Two, full knowledge. You come up slightly short on that one, because simply being told so does not mean “full knowledge”. It means understanding its as well, otherwise the knowledge is incomplete.
Where you miss the point completely is on full consent of the will. A long-term sexual relationship might not be easy to break for many folks. Let’s see what the Holy Father said in Amoris Laetitia:
Note that he is quoting straight from the CCC. This is Catholic doctrine. That simply being told that a grave matter is a mortal sin makes one mortally culpable, is not.
That was I have an issue with - previous teaching states that the objective
grave matter, means you cannot receive Holy Communion in this case, now it seems to be saying judgement in this situation should be
subjective. See the parts of the documents I have posted below.
APOSTOLIC EXHORTATION FAMILIARIS CONSORTIO OF POPE JOHN PAUL II TO THE EPISCOPATE TO THE CLERGY AND TO THE FAITHFUL OF THE WHOLE CATHOLIC CHURCH ON THE ROLE OF THE CHRISTIAN FAMILY IN THE MODERN WORLD (22 Nov 1981)

They are unable to be admitted thereto from the fact that their state and condition of life
objectively contradict that union of love between Christ and the Church which is signified and effected by the Eucharist. Besides this, there is another special pastoral reason: if these people were admitted to the Eucharist, the faithful would be led into error and confusion regarding the Church’s teaching about the indissolubility of marriage.
CONGREGATION FOR THE DOCTRINE OF THE FAITH
LETTER TO THE BISHOPS OF THE CATHOLIC CHURCH
CONCERNING THE RECEPTION OF HOLY COMMUNION
BY THE DIVORCED AND REMARRIED MEMBERS OF THE FAITHFUL (14 Sept 1994)

Prefect

With respect to the aforementioned new pastoral proposals, this Congregation deems itself obliged therefore to recall the doctrine and discipline of the Church in this matter. In fidelity to the words of Jesus Christ(5), the Church affirms that a new union cannot be recognised as valid if the preceding marriage was valid. If the divorced are remarried civilly, they find themselves in a situation that
objectively contravenes God’s law. Consequently, they cannot receive Holy Communion as long as this situation persists(6).
This norm is not at all a punishment or a discrimination against the divorced and remarried, but rather expresses an **objective situation **that of itself renders impossible the reception of Holy Communion: “They are unable to be admitted thereto from the fact that their state and condition of life objectively contradict that union of love between Christ and his Church which is signified and effected by the Eucharist. Besides this, there is another special pastoral reason: if these people were admitted to the Eucharist, the faithful would be led into error and confusion regarding the Church’s teaching about the indissolubility of marriage”(7).
