Note.—"In Jesus" is not a scriptural expression as to people—we have "the truth as it is in Jesus." It is in Christ Jesus; Jesus is the name of the Person who is Jehovah the Savior—Christ is His office and relative place. So too the name of "Church of God"; "Church of Christ" is human, and not used in Scripture. "Church of God "is that which Scripture used and raises the thought and idea of the Church far higher, and gives it a reality and a meaning.
I add a remark, made long ago, proving that Scripture is much more accurate than we think in these matters; it is never said "God loved the Church," nor that "Christ loved the world." Christ's love of the Church is connected with relationship—God's love of the world with His character.
