It has been claimed, recently, that the fact that all the non-gravitational fields are
locally Poincar´e invariant and that these invariances coincide, in a certain regime,
with the symmetries of the spacetime metric is miraculous in general relativity (GR).
In this paper I show that, in the context of GR, it is possible to account for these
so-called miracles of relativity. The way to do so involves integrating the realisation
that the gravitational field equations (the Einstein field equation in GR) impose
constraints on the behaviour of matter in a novel interpretation of the equivalence
principle, which dictates the determination of local inertial frames through gravitational
interaction. This proposed explanation of the miracles can also deal with
the problematic cases for attempts at explaining them in the context of the standard
geometrical perspective on relativity theory.
