"...we must first scrutinize thoroughly anything appearing in our hearts or any saying suggested to us. Has it come purified from the divine and heavenly fire of the Holy Spirit? Or does it lean toward Jewish superstition? Is its surface piety something which has come down from bloated worldly philosophy? We must examine this most carefully, doing as the apostle bids us: 'Do not believe in every spirit, but make sure to find out if spirits are from God'."

The heavenly Father Whom we worship is the Father of the Truth, namely, of the only-begotten Son, and has the Spirit of Truth, the Holy Spirit, and those who worship Him in these Two do so because they believe in these Persons and act through Them. For the Apostle tells us that it is through the Spirit that we worship and pray (cf. Rom. 8:26), and God's only-begotten Son says, 'No man cometh unto the Father, but by Me' (John 14:6).
