A lyrical passage from Teilhard de Chardin on world religions and the Incarnation

Fr. Teilhard de Chardin describes this progressive revelation of the Trinity, culminating in Christ who integrally and explicitly revealed it:

"...the fearful, anonymous labors of primitive man,
the beauty fashioned through the age-long history
by ancient Egypt,
the anxious expectancies of Israel,
the patient distilling of the attar of oriental mysticism,
the endless refining of wisdom by the Greeks;
all these were needed before the Flower
could blossom on the rod of Jesse
and of all humanity.
All these preparatory processes
were cosmically and biologically necessary
that Christ might set foot on the human stage."
