On the contrary, It is stated (Apoc. 10:6) that the angel who appeared, "swore by him that liveth for ever and ever . . . that time shall be no longer," namely after the seventh angel shall have sounded the trumpet, at the sound of which "the dead shall rise again" (1 Cor. 15:52). Now if time be not, there is no movement of the heaven. Therefore the movement of the heaven will cease.
Further: "Thy sun shall go down no more, and thy moon shall not decrease" (Is. 60:20). Now the setting of the sun and the phases of the moon are caused by the movement of the heavens. Therefore the heavenly movement will cease at length.
Further, it is shown in De Gener. ii that "the movement of the heaven is for the sake of continual generation in this lower world." But generation will cease when the number of the elect is complete. Therefore the movement of the heaven will cease.
Further, all movement is for some end (Metaph. ii). But all movement for an end ceases when the end is obtained. Therefore either the movement of the heaven will never obtain its end, and thus it would be useless, or it will cease at length.
Further, rest is more noble than movement, because things are more likened to God, Who is supremely immovable, by being themselves unmoved. Now the movement of lower bodies terminates naturally in rest. Therefore since the heavenly bodies are far nobler, their movement terminates naturally in rest.
