Today’s Catechism sections discuss the Church an Earth and in Heaven. Supporting material comes from the Dogmatic Constitution, “Lumen Gentium”.

II. THE COMMUNION OF THE CHURCH OF HEAVEN AND EARTH

954 The three states of the Church. "When the Lord comes in glory, and all his angels with him, death will be no more and all things will be subject to him. But at the present time some of his disciples are pilgrims on earth. Others have died and are being purified, while still others are in glory, contemplating 'in full light, God himself triune and one, exactly as he is"':490

All of us, however, in varying degrees and in different ways share in the same charity towards God and our neighbours, and we all sing the one hymn of glory to our God. All, indeed, who are of Christ and who have his Spirit form one Church and in Christ cleave together.491

955 "So it is that the union of the wayfarers with the brethren who sleep in the peace of Christ is in no way interrupted, but on the contrary, according to the constant faith of the Church, this union is reinforced by an exchange of spiritual goods."492

956 The intercession of the saints. "Being more closely united to Christ, those who dwell in heaven fix the whole Church more firmly in holiness.... They do not cease to intercede with the Father for us, as they proffer the merits which they acquired on earth through the one mediator between God and men, Christ Jesus.... So by their fraternal concern is our weakness greatly helped."493

Do not weep, for I shall be more useful to you after my death and I shall help you then more effectively than during my life. 494

I want to spend my heaven in doing good on earth. 495

957 Communion with the saints. "It is not merely by the title of example that we cherish the memory of those in heaven; we seek, rather, that by this devotion to the exercise of fraternal charity the union of the whole Church in the Spirit may be strengthened. Exactly as Christian communion among our fellow pilgrims brings us closer to Christ, so our communion with the saints joins us to Christ, from whom as from its fountain and head issues all grace, and the life of the People of God itself"496:

We worship Christ as God's Son; we love the martyrs as the Lord's disciples and imitators, and rightly so because of their matchless devotion towards their king and master. May we also be their companions and fellow disciples! 497

958 Communion with the dead. "In full consciousness of this communion of the whole Mystical Body of Jesus Christ, the Church in its pilgrim members, from the very earliest days of the Christian religion, has honored with great respect the memory of the dead; and 'because it is a holy and a wholesome thought to pray for the dead that they may be loosed from their sins' she offers her suffrages for them."498 Our prayer for them is capable not only of helping them, but also of making their intercession for us effective.

959 In the one family of God. "For if we continue to love one another and to join in praising the Most Holy Trinity - all of us who are sons of God and form one family in Christ - we will be faithful to the deepest vocation of the Church."499

IN BRIEF

962 "We believe in the communion of all the faithful of Christ, those who are pilgrims on earth, the dead who are being purified, and the blessed in heaven, all together forming one Church; and we believe that in this communion, the merciful love of God and his saints is always [attentive] to our prayers" (Paul VI, CPG # 30).

The Dogmatic Constitution, “Lumen Gentium” (49, 50) discusses the union of the members in the Church in Heaven and on Earth.

49. Until the Lord shall come in His majesty, and all the angels with Him (266) and death being destroyed, all things are subject to Him,(277) some of His disciples are exiles on earth, some having died are purified, and others are in glory beholding "clearly God Himself triune and one, as He is";(1*) but all in various ways and degrees are in communion in the same charity of God and neighbor and all sing the same hymn of glory to our God. For all who are in Christ, having His Spirit, form one Church and cleave together in Him.(268) Therefore the union of the wayfarers with the brethren who have gone to sleep in the peace of Christ is not in the least weakened or interrupted, but on the contrary, according to the perpetual faith of the Church, is strengthened by communication of spiritual goods.(2*) For by reason of the fact that those in heaven are more closely united with Christ, they establish the whole Church more firmly in holiness, lend nobility to the worship which the Church offers to God here on earth and in many ways contribute to its greater edification.(269)(3*) For after they have been received into their heavenly home and are present to the Lord,(270) through Him and with Him and in Him they do not cease to intercede with the Father for us,(4*) showing forth the merits which they won on earth through the one Mediator between God and man,(271) serving God in all things and filling up in their flesh those things which are lacking of the sufferings of Christ for His Body which is the Church.(272)(5*) Thus by their brotherly interest our weakness is greatly strengthened.

50. Fully conscious of this communion of the whole Mystical Body of Jesus Christ, the pilgrim Church from the very first ages of the Christian religion has cultivated with great piety the memory of the dead,(6*) and "because it is a holy and wholesome thought to pray for the dead that they may be loosed from their sins",(273) also offers suffrages for them. The Church has always believed that the apostles and Christ's martyrs who had given the supreme witness of faith and charity by the shedding of their blood, are closely joined with us in Christ, and she has always venerated them with special devotion, together with the Blessed Virgin Mary and the holy angels.(7*) The Church has piously implored the aid of their intercession. To these were soon added also those who had more closely imitated Christ's virginity and poverty,(8*) and finally others whom the outstanding practice of the Christian virtues (9*) and the divine charisms recommended to the pious devotion and imitation of the faithful.(10*)
