But what will it be to behold hereafter so many angels, so many just men, to be united with them in the closest friendship, and to be made partakers of their happiness? Were we to behold, in this our exile, one angel arrayed in all his beauty, who would not eagerly wish to meet him? What therefore must it be, to behold all the angels in one place? And if only one of the prophets, apostles, or doctors of the Church were to descend from heaven, with what curiosity and attention would he be heard! Now in the kingdom of God, we shall be allowed to behold not one only, but all the prophets, apostles, and doctors, with whom we shall continually hold sweet converse.
--St. Robert Bellarmine, The Eternal Happiness of the Saints
