You also, as living stones, are built up as a spiritual house, to be a holy priesthood, to offer up spiritual sacrifices, acceptable to God through Jesus Christ.
This is the true metaphor, and which has not, as far as I know, ever been properly traced out. To talk of "stones being said to be alive as long as they are not cut out of the quarry, but continue to partake of that nourishment which circulates from vein to vein," is as unsatisfactory as it is unphilosophical; the other is the true metaphor, and explains every thing.
