The two points to be considered in reference to this subject, are, first the nature, and second the office or work of the Holy Spirit. With regard to his nature, is He a person or a mere power? and if a person, is He created or divine, finite or infinite? The personality of the Spirit has been the faith of the Church from the beginning. It had few opponents even in the chaotic period of theology; and in modern times has been denied by none but Socinians, Arians, and Sabellians. Before considering the direct proof of the Church doctrine that the Holy Spirit is a person, it may be well to remark, that the terms “The Spirit,” “The Spirit of God,” “The Holy Spirit,” and when God speaks, “My Spirit,” or, when God is spoken of “His Spirit,” occur in all parts of Scripture from Genesis to Revelation; These and equivalent terms are evidently to be understood in the same sense throughout the Scriptures.

If the Spirit of God which moved on the face of the waters, which strove with the antediluvians, which came upon Moses, which gave skill to artisans, and which inspired the prophets, is the power of God; then the Spirit which came upon the Apostles, which Christ promised to send as a comforter and advocate, and to which the instruction, sanctification, and guidance of the people of God are referred, must also be the power of God. But if the Spirit is clearly revealed to be a person in the later parts of Scripture, it is plain that the earlier portions must be understood in the same way. One part of the Bible, and much less one or a few passages must not be taken by themselves, and receive any interpretation which the isolated words may bear, but Scripture must interpret Scripture. Another obvious remark on this subject is, that the Spirit of God is equally prominent in all parts of the word of God. His intervention does not occur on rare occasions, as the appearance of angels, or the Theophanies, of which mention is made here and there in the sacred volume; but He is represented as everywhere present and everywhere operative. We might as well strike from the Bible the name and doctrine of God, as the name and office of the Spirit.
