The Christian heaven is Christian truth. That which its excluded from heaven is excluded from true Christianity. In heaven the Christian is free from that which he wishes to be free from here--free from the sexual impulse, free from matter, free from Nature in general. "In the resurrection they neither marry nor are given in marriage, but are as the angels of God in heaven."--Matt. xxii. 30. "Meats for the belly, and the belly for meats; but God shall destroy (katargesei, make useless) both it and them."--1 Cor. vi. 13. "Now this I say, brethren, that flesh and blood cannot inherit the kingdom of heaven, neither doth corruption inherit incorruption."--Ib. xv. 50. "They shall hunger no more, neither thirst any more; neither shall the sun light on them, nor any heat."--Rev. vii. 16. "And there shall be no night there; and they need no candle, neither light of the sun."--Ib. xxii. 5. "Comedere, bibere, vigilare, dormire, quiescere, laborare et caeteris necessitatibus naturae subjacere, vere magna miseria est et afflictio homini devoto, qui libenter esset absolutus et liber ab omni peccato. Utinam non essent istae necessitates, sed solum spirituales animae refectiones, quas heu! satis raro degustamus."--Thomas à K. (de Imit. 1. i. cc. 22, 25). See also on this subject S. Gregorii Nyss. de Anima et Resurr., Lipsiae, 1837, pp. 98, 144, 153). It is true that the Christian immortality, in distinction from the heathen, is not the immortality of the soul, but that of the flesh, that is, of the whole man. "Scientia immortalis visa est res illis (the heathen philosophers) atque incorruptibilis. Nos autem, quibus divina revelatio illuxit ... novimus, non solum mentem, sed affectus perpurgatos, neque animam tantum, sed etiam corpus ad immortalitatem assumptum iri suo tempore."--Baco de Verul. (de Augm. Scien. 1. i.). On this account Celsus reproached the Christians with a desiderium corporis. But this immortal body is, as has been already remarked, an immaterial, i.e., a thoroughly fanciful, subjective body--a body which is the direct negation of the real, natural body. The ideal on which this faith hinges is not the recognition or glorification of nature, of matter as such, but rather the reality of the emotive imagination, the satisfaction of the unlimited, supranaturalistic desire of happiness, to which the actual, objective body is a limitation.
