Lumen Gentium Chapter VII : The Pilgrim Church - paragraph 48
The Church (we) will only reach perfection in the next life. Here we struggle the best we can in Jesus Christ. The word ‘catholic’ means ‘universal’ and as such the Church is set up by God as the sacrament of salvation for all leading them to that next-life perfection. Here Christ is still active in the world leading us toward that place where He reigns with the Father. He nourishes us with His Body and Blood, guides us with the Holy Spirit toward the promised restoration of our original state for which we were intended: walking in perfection with our God.
The battle is already won. It is not like a movie where we sit on the edge of our seat wondering if the forces of good or evil will win. Christ has already claimed victory, though the vestiges of the battle still linger in this life. But even now the restoration is taking place. We are on the path. The goal is in view. There are many temptations wooing us off of the path. “Stop here and enjoy my delights.” But these will pass. We are called to forge onward to our true home; the only place we will be fully happy – the place where our long desired for inheritance awaits.
