This is the reason for placing it by itself, followed by the congruence theorems.
The aim of this lecture is to establish a theory of congruence.
You must understand at once that congruence is a controversial question.
Finally the sixth axiom of congruence is that the relation of congruence is transitive.
The source of order has already been indicated and that of congruence is now found.
The meaning of congruence lies beyond the self-identity of the object.
This lack of congruence between the mental picture and the object itself is necessary for obvious reasons.
The congruence of the Spirit and the body of the Church, if it occurs, is purely accidental.
Congruence means a close match between what you feel and how you think and act.
We shall find in the next lecture that it is from this symmetry that the theory of congruence is deduced.
