Input to this topic : letter of the CONGREGATION FOR THE DOCTRINE OF THE FAITH dated 1979
"7) In fidelity to the New Testament and Tradition, the Church believes in the happiness of the just who will one day be with Christ. She believes that there will be eternal punishment for the sinner, who will be deprived of the sight of God, and that this punishment will have a repercussion on the whole being of the sinner. She believes in the possibility of a purification for the elect before they see God, a purification altogether different from the punishment of the damned. This is what the Church means when speaking of Hell and Purgatory.
When dealing with man's situation after death, one must especially beware of arbitrary imaginative representations: excess of this kind is a major cause of the difficulties that Christian faith often encounters. Respect must however be given to the images employed in the Scriptures. Their profound meaning must be discerned, while avoiding the risk of over-attenuating them, since this often empties of substance the realities designated by the images
Neither Scripture nor theology provides sufficient light for a proper picture of life after death. Christians must firmly hold the two following essential points: on the one hand they must believe in the fundamental continuity, thanks to the power of the Holy Spirit, between our present life in Christ and the future life (charity is the law of the Kingdom of God and our charity on earth will be the measure of our sharing in God's glory in heaven); on the other hand they must be clearly aware of the radical break between the present life and the future one, due to the fact that the economy of faith will be replaced by the economy of fullness of life: we shall be with Christ and "we shall see God" (cf. 1 Jn 3:2), and it is in these promises and marvellous mysteries that our hope essentially consists. Our imagination may be incapable of reaching these heights, but our heart does so instinctively and completely."
