The Shepherd of Hermas

When, therefore, it had lived nobly and purely, and had laboured with the Spirit, and worked with it in every deed, behaving with power and bravery, he chose it as companion with the Holy Spirit;[*](The meaning is apparently that the flesh (i.e. the human being?), in which the Spirit had been incarnate, was elevated to be the companion, for the future, of the Father and of the Son who is the Spirit.) for the conduct

Therefore he took the Son and the glorious angels as counsellors, that this flesh also, having served the Spirit blamelessly, should have some place of sojourn, and not seem to have lost the reward of its service. For all flesh in which the Holy Spirit has dwelt shall receive a reward if it be found undefiled and spotless.

You have the explanation of this parable also.

I am glad, sir, said I, to hear this explanation.[*](The practical conclusion) Listen, now, he said. Guard this flesh of yours, pure and undefiled, that the spirit which dwells in it may bear it witness, and your flesh may be justified.

See to it, lest the idea enter your heart that this flesh of yours is mortal, and you abuse it in some defilement. For if you defile your flesh you defile also the Holy Spirit, and if you defile the flesh you shall not live.
