"To say that the human soul, angels, god, are immaterial, is to say they are nothings, or that there is no god, no angels, no soul. I cannot reason otherwise: but I believe I am supported in my creed of materialism by Locke, Tracy, and Stewart. At what age of the Christian church this heresy of immaterialism, this masked atheism, crept in, I do not know. But a heresy it certainly is. Jesus taught nothing of it. He told us indeed that `God is a spirit,' but he has not defined what a spirit is, nor said that it is not matter. And the antient fathers generally, if not universally, held it to be matter: light and thin indeed, an etherial gas; but still matter. Origen says `Deus reapse corporalis est; sed graviorum tantum corporum ratione, incorporeus.' Tertullian `quid enim deus nisi corpus?' and again `quis negabit deumesse corpus? Etsi deus spiritus, spiritus etiam corpus est, sui generis, in sua effigie.' St. Justin Martyr `{to Theion phamen einai asomaton oyk oti asomaton -- epeide de to me krateisthai ypo tinos, toy krateisthai timioteron esti, dia toyto kaloymen ayton asomaton.}' And St. Macarius, speaking of angels says `quamvis enim subtilia sint, tamen in substantia, forma et figura, secundum tenuitatem naturae eorum, corpora sunt tenuia.' And St. Austin, St. Basil, Lactantius, Tatian, Athenagoras and others, with whose writings I pretend not a familiarity, are said by those who are, to deliver the same doctrine. [...] I am satisfied, and sufficiently occupied with the things which are, without tormenting or troubling myself about those which may indeed be, but of which I have no evidence."
