Thomas Aquinas, on Heb 12:22

“But you are come to mount Sion, and to the city of the living God, the heavenly Jerusalem, and to the company of many thousands of angels,”

“705. – Then he mentions the conditions of the New Testament, saying: But you have come to Mount Zion, and to the city of the living God. Here he shows the things proposed to us in it; and three things are promised to us, namely, the hope of future glory, participation in the Church, and familiarity with God. 706. – In heavenly glory there are two things which will particularly gladden the just, namely, the enjoyment of the godhead and companionship with the saints. For no good is joyfully possessed without companions, as Boethius says: and in Ps. 132 (v. 1): 'Behold how good and how pleasant it is for brethren to dwell together.' But enjoyment consists in two things, namely, in the intellect's vision and in the will's delight. For, as Augustine says: 'We enjoy the things we know, in which the delighted will rests.' Because of the vision he says, You have come to mount Zion, for Zion signifies the loftiness of divine contemplation: 'Look upon Zion, the city of our solemnity' (Is. 33:20). The gladness and pleasure of the will is signified by the heavenly Jerusalem, and to the city of the living God: 'Jerusalem, which is built as a city' (Ps. 121:3); 'Who has placed peace in your borders: and filled you with the fat of corn' (Ps. 147:12, 14); 'That Jerusalem which is above is free' (Gal. 4:26). Hence, there will be nothing further to be desired: 'Since I am become in his presence as one finding peace' (S of S 8:10). 707. – But an additional joy will be the company of the saints, of whom he says, and to innumerable angels: 'Their angels always see the face of my Father in heaven' (Mt. 18:10). That there are thousands is clear from Dan (7:10): 'Thousands of thousands ministered to him, and ten thousand times a hundred thousand stood before him'; 'Is there any numbering of his soldiers?' (Jb. 25:3); 'And the number of them was thousands of thousands' (Rev. 5:11).”
