Ah well, it's revelation, that changes everything.
Yes. On that issue, the faithful agrees with the secular:
"Deus Caritas Est" (
God is Love), Pope Benedict XVI. And,
"Love, love changes everything: how you live and how you die" (A.L. Weber).
What you call revelation and what @Bradskii calls reasoning may be born from the same source.
Not likely. The right relationship of revelation to reason gives the former primacy.
Another of the great insights of Saint Thomas was his perception of the role of the Holy Spirit in the process by which knowledge matures into wisdom. From the first pages of his Summa Theologiae, Aquinas was keen to show the primacy of the wisdom which is the gift of the Holy Spirit and which opens the way to a knowledge of divine realities. His theology allows us to understand what is distinctive of wisdom in its close link with faith and knowledge of the divine. This wisdom comes to know by way of connaturality; it presupposes faith and eventually formulates its right judgement on the basis of the truth of faith itself: “The wisdom named among the gifts of the Holy Spirit is distinct from the wisdom found among the intellectual virtues. This second wisdom is acquired through study, but the first 'comes from on high', as Saint James puts it. This also distinguishes it from faith, since faith accepts divine truth as it is. But the gift of wisdom enables judgement according to divine truth”.
("Fides et Ratio" p. 44, St. John Paul II).
What does truly mean here? Because the feelings are true and they define wrong or right for me.
Truth is singular and independent of the the thinking or feeling human mind. An individualistic ethic, especially one based on feelings, by definition, is not likely to be instructive to the many.
These considerations apply equally to moral theology. It is no less urgent that philosophy be recovered at the point where the understanding of faith is linked to the moral life of believers. ... [M]any of the problems of the contemporary world stem from a crisis of truth. I noted that “once the idea of a universal truth about the good, knowable by human reason, is lost, inevitably the notion of conscience also changes. Conscience is no longer considered in its prime reality as an act of a person's intelligence ... Instead, there is a tendency to grant to the individual conscience the prerogative of independently determining the criteria of good and evil and then acting accordingly. Such an outlook is quite congenial to an individualist ethic, wherein each individual is faced with his own truth different from the truth of others” (Ibid p. 98).
