We have spoken of essential beatitude, which consists in the immediate vision of God and in the love which flows from this vision. But the Lord, so rich in mercy for His elect, adds to essential beatitude a joy in created good, a joy which corresponds to their aspirations. This is what we call accidental beatitude.
This accidental beatitude is found in the society of friends: in general joy at the good deeds done on earth: in the special recompense given to certain classes, the halo of virgins, for example, of doctors, and of martyrs: in the resurrection and in the qualities of the glorious body.
Accidental Beatitude in the Soul
In regard to those whom they have known and loved on earth, the saints receive, besides the beatific vision in Verbo, also new knowledge extra Verbum. It is an accidental joy to learn, for example, of the spiritual progress, of their friends on earth, to see them entering heaven. This knowledge extra Verbum, is inferior to the beatific vision. Hence some call it the evening vision, contrasted with the morning vision which sees created things in God.
Further, each soul is happy to be honored by God, by the friends of God, especially by those who shine by wisdom. Each has a special joy in seeing his own good recognized and appreciated, good which he accomplished on earth in the midst of great difficulties.
Special recompense will be given for victories gained against the flesh, the world, and the devil: the halo of virgins, for victory against the concupiscence of the flesh: the halo of the martyrs for victory over persecutors: the halo of doctors for victory over ignorance, errors, infidelity, heresy, over the spirit of division and negation. This halo belongs, not only to those who have publicly taught sacred science, by word or by pen, but also to those who have taught in private fashion when occasion presented itself. "They that instruct many to justice shall shine as stars for all eternity." This halo belongs, first to the spirit, then, after the resurrection, to the body, just as the essential glory of the soul is reflected in the body raised from the dead.
