"Lumen gentium", the Second Vatican Council's dogmatic constitution on the Church

The eschatological character of the pilgrim Church

The Church, to which we are all called in Christ Jesus and in which we acquire holiness through the grace of God, will reach its perfection only in the glory of heaven, when the time comes for the renewal of all things, and the whole world, which is intimately bound up with man and reaches its perfection through him, will, along with the human race, be perfectly restored in Christ.

  Lifted above the earth, Christ drew all things to himself. Rising from the dead, he sent his life-giving Spirit upon his disciples, and through the Spirit established his Body, which is the Church, as the universal sacrament of salvation. Seated at the right hand of the Father, he works unceasingly in the world, to draw men into the Church and through it to join them more closely to himself, nourishing them with his own body and blood, and so making them share in his life of glory.

  The promised renewal that we look for has already begun in Christ. It is continued in the mission of the Holy Spirit. Through the Spirit it goes on developing in the Church: there we are taught by faith about the meaning also of our life on earth as we bring to fulfillment – with hope in the blessings that are to come – the work that has been entrusted to us in the world by the Father, and so work out our salvation.

  The end of the ages is already with us. The renewal of the world has been established, and cannot be revoked. In our era it is in a true sense anticipated: the Church on earth is already sealed by genuine, if imperfect, holiness. Yet, until a new heaven and a new earth are built as the dwelling place of justice, the pilgrim Church, in its sacraments and institutions belonging to this world of time, bears the likeness of this passing world. It lives in the midst of a creation still groaning and in travail as it waits for the sons of God to be revealed in glory.
