“The person of Jesus is unprecedented and therefore measurable by no already existing norm. Christian recognition consists of realizing that all things really began with Jesus Christ; that he is his own norm – and therefore ours – for he is truth.
“Christ’s effect upon the world can be compared with nothing in its history save its own creation: ‘In the beginning God created heaven and earth.’ What takes place in Christ is of the same order as the original act of creation, though on a still higher level. For the beginning of the new creation is as far superior to the love which created the stars, plants, animals and men. That is what the words mean: ‘I have come to cast fire upon the earth, and what will I but that it be kindled?’ (Lk. 12, 49). It is the fire of new becoming; not only ‘truth’ or ‘love,’ but the incandescence of new creation…. Down, down through terrible destruction he descends, to the nadir of divine creation whence saved existence can climb back into being.
Now we understand what St. Paul meant with his ‘excelling knowledge of Jesus Christ:’ the realization that this is who Christ is, the Descender. To make this realization our own is the alpha and omega of our lives, for it is not enough to know Jesus only as the Savior. With this supreme knowledge serious religious life can begin, and we should strive for it with our whole strength and earnestness, as a man strives to reach his place in his profession; as a scientist wrestles with the answer to his problem; as one labors at his life work or for the hand of someone loved above all else.
Are these directives for saints? No, for Christians… One day he will come. Once in the stillness of profound composure you will know: that is Christ! Not from a book or the word or someone else, but through him. He who is creative love brings your intrinsic potentialities to life. Your ego at its profoundest is he” (Romano Guardini, “The Lord,” Regnery  306);  357-358).
“Your ego at its profoundest is he:” This is the message of Gaudium et Spes #22: that Christ is the meaning of man. And St. Josemaria Escriva said: “With all our personal defects and limitations, we are other Christs, Christ himself…”
Now, consider Gregory of Nyssa:
“The reign of life has begun, the tyranny of death is ended. A new birth has taken place, a new life has come, a new order of existence has appeared, our very nature has been transformed! This birth is not brought about by human generation, by the will of man, or by the desire of the flesh, but by God.
“If you wonder how, I will explain in clear language. Faith is the womb that conceives this new life, baptism the rebirth by which it is brought forth into the light of day. The Church is its nurse; her teachings are its milk, the bread from heaven is its food. It is brought to maturity by the practice of virtue; it is wedded to wisdom; it gives birth to hope. Its home is the kingdom; its rich inheritance the joys of paradise; its end, not death, but the blessed and everlasting life prepared for those who are worthy.
“This is the day the Lord has made – a day far different from those made when the world was first created and which are measured by the passage of time. This is the beginning of a new creation. On this day, as the prophet says, God makes a new heaven and a new earth. What is this new heaven? you may ask. It is the firmament of our faith in Christ. What is the new earth? A good heart, a heart like the earth, which drinks up the rain that falls on it and yields a rich harvest.
“In this new creation, purity of life is the sun, the virtues are the stars, transparent goodness is the air, and the depths of the riches of wisdom and knowledge, the sea. Sound doctrine, the divine teachings are the grass and plants that feed God’s flock, the people whom he shepherds; the keeping of the commandments is the fruit borne by the trees.
“On this day is created the true man, the man made in the image and likeness of God. For this day the Lord has made is the beginning of this new world. Of this day the prophet says that it is not like other days, nor is this night like other nights. But still we have not spoken of the greatest gift it has brought us. This day destroyed the pangs of death and brought to birth the firstborn of the dead.
“I ascend to my Father and to your Father, to my God and to your God. O what wonderful good news! He who for our sake became like us in order to make us his brothers, now presents to his true Father his own humanity in order to draw all his kindred up after him” (Monday, Office of Readings of the Fifth Week of Easter)
