Teilhard argues that the universe has been moving in a consistent direction since the Big Bang: from simplicity to complexity, from matter to life, from life to reflective consciousness. This is not random variation but a directed process — complexification coupled with increasing interiority. As the noosphere develops and human minds interweave through communication, culture, and love, this convergence accelerates toward a point of maximum consciousness and unity.
The Omega Point must have certain properties to serve as evolution's attractor. It must be actual rather than merely potential — a pole that already exists, drawing the process toward itself, not merely a limit approached asymptotically. It must be personal, since consciousness is personal and convergence is a convergence of persons. It must be autonomous, subsisting independently of the process it draws, so that the final synthesis is not simply absorbed into nothingness but preserved. And it must be supremely loving, since only love can unite while leaving persons intact.
For Teilhard, these properties are precisely those of the Christ of Christian theology — the universal, cosmic Christ of the Pauline epistles, not merely the historical Jesus of Nazareth. The Incarnation is thus not an intervention from outside the evolutionary process but its central event: the universe becoming personal, conscious, and unified in the person of Christ. The Omega Point is where cosmogenesis becomes Christogenesis — where evolution becomes explicitly what it always was implicitly.
The Omega Point is developed throughout The Phenomenon of Man (1955), but most fully in Part IV, "Survival." Its theological implications are worked out in The Divine Milieu and in the essays collected in Christianity and Evolution.
