31 And thou shalt speak unto the children of Israel, saying, This shall be an holy anointing oil unto me throughout your generations.

32 Upon man’s flesh shall it not be poured, neither shall ye make any other like it, after the composition of it: it is holy, and it shall be holy unto you.

33 Whosoever compoundeth any like it, or whosoever putteth any of it upon a stranger, shall even be cut off from his people.

The usage of the holy anointing oil was to be exclusive to the tabernacle. It wasn’t a complicated recipe, so anyone could have recreated it, but that would result in exile. And it was to never be applied to a non-Israelite.

The path to discipleship is open to all, and was so among the ancient Israelites, but these things have to be done in the proper order. Acceptance into the fold of the church and forgiveness for sin are the first steps, and they must be taken before all of the sacraments that follow. So, too, an ancient Canaanite would first have to observe the Passover, join the Israelite nation, and bring sacrifice to the tabernacle to enjoy the blessings of those anointed vessels.

This anointing oil was also not to be placed directly upon the flesh either. The priests would be anointed by it, but so far we have only heard of that being done by sprinkling it over their clothes. There is also a historical idea of anointing oil being applied to the head, but perhaps a few drops on the hair would not be considered as being applied to the flesh.
