My Dear Sweet Freinds,
First, Christianity is not a religion per se, as most think it is. Christianity is the path of all existence that continually work its Way back to the Creator.
Christianity is God in expression through the activities of mankind. This activity is Love, and only Love. Any expression of Love in the world is the work of Christianity as the only path for all creation back to the Creator. Not as a religion, placing itself above all religions, but as Love Itself, the Son of Love as expressed in the acts of man.
So, in the final analysis, Christianity is Love Itself, expressed one man unto another upon Earth. As Jesus said, by this shall the world know that ye art my disciples.
