Canto XXIV. Beatrice and Dante are now joined by the spirit of St. Peter, who examines Dante on faith, receiving the famous reply: "Faith is the substance of the thing we hope for, and evidence of those that are not seen." Not only does St. Peter approve Dante's definition, but he discusses theological questions with him, leading him meanwhile further into this sphere.

Canto XXV. Presently a spirit approaches them which is designated by Beatrice as St. James. After greeting St. Peter and smiling upon Beatrice, St. James reveals he has been sent hither by Christ to examine Dante upon hope, whereupon our poet, lifting his eyes "to the hills," gains courage enough to answer thus: "Hope is the certain expectation of future glory, which is the effect of grace divine and merit precedent." St. James is so pleased with this answer that he glows even more brightly, as St. John, "who lay upon the breast of him, our Pelican," appeared, shining so brightly that Dante, turning to ask Beatrice who he is, discovers he can no longer see her although she is close beside him.

"I turn'd, but ah! how trembled in my thought,
When, looking at my side again to see
Beatrice, I descried her not; although,
Not distant, on the happy coast she stood."

Canto XXVI. Dante now ascertains he has merely been temporarily blinded by the excess of light which emanates from St. John, who proceeds to examine him in regard to Charity. His answers are greeted by the heavenly chorus with the chant "Holy, holy, holy," in which Beatrice joins, ere she clears the last mote away from Dante's eyes and thus enables him to see more plainly than ever. Our poet now perceives a fourth spirit, in whom he recognizes Adam, father of mankind, who retells the story of Eden, adding that, 4232 years after creation, Christ delivered him from hell, and enabled him to view the changes which had taken place in the fortunes of his descendants during that long space of time.

Canto XXVII. After listening enraptured to the melody of the heavenly choir chanting "Glory be to the Father, to the Son, and to the Holy Ghost," Dante gazes upon the four worthies near him, who glow and shine like torches, while "silence reigns in heaven." Then St. Peter, changing color, holds forth against covetousness, and expounds the doctrine of apostolic succession. Because the early popes died as martyrs, he considers it a disgrace that their successors should be guilty of misgovernment. He adds that the keys bestowed upon him should never figure on banners used in waging unrighteous wars, and that his effigy on the papal seal should never appear on worldly documents.

Then Beatrice affords Dante a glimpse of the earth from the Straits of Gibraltar to the Bosphorus, and, when this vision ends, wafts him up into the ninth heaven, the Primum Mobile, or spot whence all motion starts, although itself remains immovable.

Here is the goal, whence motion on his race
Starts: motionless the centre, and the rest
All moved around.

Canto XXVIII. From this point Dante watches the universe spin around him, until "she who doth emparadise my soul" draws aside the veil of mortality, and allows him to perceive nine concentric spheres of multitudinous angels constantly revolving around a dazzling point while singing "Hosanna!" These are the heavenly host, the hierarchy of angels, Seraphim, Cherubim, Thrones, Dominations, Virtues, Powers, Princedoms, Archangels, and Angels, in charge of the various circles which compose Dante's Paradise.

Canto XXIX. Able to read Dante's thoughts, Beatrice explains some of the things he would fain know, and disperses his doubts, cautioning him, if he would be blessed, to rid himself of every atom of pride, since that caused even angels to fall!

Canto XXX. Once more Dante's eyes are fixed upon Beatrice, whose beauty far transcends his powers of description, and is by her conveyed into the next circle, the Empyrean, or heaven of pure light, into which he is told to plunge as into a river. Eagerly quaffing its ethereal waters to satisfy his ardent thirst for knowledge, Dante beholds the court of Heaven, and descries its myriads of thrones, all occupied by redeemed spirits. These thrones are grouped around a brilliant centre (God) so as to form a dazzling jewelled rose.
