Theodotus Demonstrates that the Sacraments Were Transformed by the Presence of the Divine Name

And the bread and the oil are sanctified by the power of the Name, and they are not the same as they appeared to be when they were received, but they have been transformed by power into spiritual power. Thus, the water, also, both in exorcism and baptism, not only keeps off evil, but gives sanctification as well. (Ex. 82)

I suspect the sacraments literally had the divine Name imprinted on it (in the case of the oil perhaps etched on the container).
