Is the Holy Spirit who is meant by the phrase "He who now letteth" in 2 Thessalonians?

Who is the person referred to in 2 Thessalonians 2:7 as "He who now letteth will let, until He be taken out of the way"?

There have been many suggestions given as to the identity of this restrainer. It is a spiritual conflict that is in view. We believe then, that a Divine Person is required to satisfy the context of the passage. We feel this rules out the two most common theories, that "He who hindereth" is the Roman Empire or Satan. The first has not the power and the latter has not the purpose. Mark 3:25 says, "If a house be divided against itself, that house cannot stand." We suggest that the Holy Spirit in the Church is the "Restrainer" of Satan's man of sin. He will "be taken out of the way" (verse 7). We regard this as the Spirit of God going with the Church at the rapture. This does not mean He will cease to operate in the world, but His mode of working will revert to His activity in Old Testament days.
