1Cor 10, 1-6 And the rock was the Christ

1Corinthians 10

(1Cor 10, 1-6) And the rock was the Christ

[1] I do not want you to be unaware, brothers, that our ancestors were all under the cloud and all passed through the sea, [2] and all of them were baptized into Moses in the cloud and in the sea. [3] All ate the same spiritual food, [4] and all drank the same spiritual drink, for they drank from a spiritual rock that followed them, and the rock was the Christ. [5] Yet God was not pleased with most of them, for they were struck down in the desert. [6] These things happened as examples for us, so that we might not desire evil things, as they did.

(CCC 697) Cloud and light. These two images occur together in the manifestations of the Holy Spirit. In the theophanies of the Old Testament, the cloud, now obscure, now luminous, reveals the living and saving God, while veiling the transcendence of his glory - with Moses on Mount Sinai (Cf. Ex 24:15-18), at the tent of meeting (Cf. Ex 33:9-10), and during the wandering in the desert (Cf. Ex 40:36-38; 1 Cor 10:1-2), and with Solomon at the dedication of the Temple (Cf. 1 Kings 8:10-12). In the Holy Spirit, Christ fulfills these figures. The Spirit comes upon the Virgin Mary and "overshadows" her, so that she might conceive and give birth to Jesus (Lk 1:35). On the mountain of Transfiguration, the Spirit in the "cloud came and overshadowed" Jesus, Moses and Elijah, Peter, James and John, and "a voice came out of the cloud, saying, 'This is my Son, my Chosen; listen to him!'" (Lk 9:34-35). Finally, the cloud took Jesus out of the sight of the disciples on the day of his ascension and will reveal him as Son of man in glory on the day of his final coming (Cf. Acts 1:9; cf. Lk 21:27). (CCC 694) Water. The symbolism of water signifies the Holy Spirit's action in Baptism, since after the invocation of the Holy Spirit it becomes the efficacious sacramental sign of new birth: just as the gestation of our first birth took place in water, so the water of Baptism truly signifies that our birth into the divine life is given to us in the Holy Spirit. As "by one Spirit we were all baptized," so we are also "made to drink of one Spirit" (1 Cor 12:13). Thus the Spirit is also personally the living water welling up from Christ crucified (Jn 19:34; 1 Jn 5:8) as its source and welling up in us to eternal life (Cf. Jn 4:10-14; 7:38; Ex 17:1-6; Isa 55:1; Zech 14:8; 1 Cor 10:4; Rev 21:6; 22:17).
