Whether the heavens should have been opened unto Christ at His baptism?

Objections

Objection 1 : It would seem that the heavens should not have been opened unto Christ at His baptism. For the heavens should be opened unto one who needs to enter heaven, by reason of his being out of heaven. But Christ was always in heaven, according to Jn. 3:13: "The Son of Man who is in heaven." Therefore it seems that the heavens should not have been opened unto Him.
Objection 2 : Further, the opening of the heavens is understood either in a corporal or in a spiritual sense. But it cannot be understood in a corporal sense: because the heavenly bodies are impassible and indissoluble, according to Job 37:18: "Thou perhaps hast made the heavens with Him, which are most strong, as if they were of molten brass." In like manner neither can it be understood in a spiritual sense, because the heavens were not previously closed to the eyes of the Son of God. Therefore it seems unbecoming to say that when Christ was baptized "the heavens were opened."
Objection 3 : Further, heaven was opened to the faithful through Christ's Passion, according to Heb. 10:19: "We have [Vulg.: 'Having'] a confidence in the entering into the holies by the blood of Christ." Wherefore not even those who were baptized with Christ's baptism, and died before His Passion, could enter heaven. Therefore the heavens should have been opened when Christ was suffering rather than when He was baptized.
