David C. Grabbe: In II John 7, the apostle John identifies an antichrist as one who denies that Jesus Christ is presently in His followers. ...
David Grabbe, describing several contexts of the term "anti-Christ," points out that one meaning of anti-Christ is those who believe that Jesus Christ is not the Messiah, but a mortal, who may have been a good teacher, but was not a Savior or a literal Son of God. Two-thirds of the Abrahamic religions—Judaism and Islam— fall into this category. The apostle John dealt with a group of false apostles in the early Church who had embraced the Gnostic teaching of Docetism, which considers anything physical impure, thereby precluding Christ's physical presence as having any consequence, but considered only the other part of the dual nature, the spiritual, worthy of worship. The teaching of Docetism led to a passive idea of repentance, causing people to accept Jesus' sacrifice and grace, but reject any attempt at overcoming and living by His laws. Sadly, most professing Christians have accepted this deception, rejecting the idea that God's Holy Spirit lives within us, prompting us to walk in His commandments, enabling spiritual growth into the stature of Jesus Christ. They may claim to follow Him, but they reject His commandments. With God's Spirit in us, prompting spiritual growth, we will mature into the fullness of Christ. Without His Spirit, we will have the spirit of anti-Christ.
In the gospel accounts, the Pharisees receive the lion's share of Christ's correction for their blatant hypocrisy, and they have become a byword for that sin. Martin Collins explores the extent of this sin, which can reach to the point of the unpardonable sin, and suggests how we can overcome it.
Richard Ritenbaugh, focusing on Peter's proclamation that Jesus Christ was the Messiah, the Christ, the Son of the living God, recognizes that after this awesome insight, Jesus realized that He could begin building His church. Sadly, the church that publically appeared in the second century was hopelessly corrupt, but appropriated the name 'Christian.' The Roman Catholic church presumed to speak for Christianity, attempting to control political and religious constituencies. The medieval (Roman Catholic) church was awash in sexual sins, as well as sins of avarice. The custodians of the 'keys to the kingdom' wielded their power to bind and loose for carte blanche control, using tithes, papal fees, papal taxes, fiefdoms, the threat of excommunication, and the selling of indulgences to increase the revenue of the church and promote tyrannical political power over secular domains. This massive, corrupt monolith was not the small flock that Jesus Christ founded, a group called and empowered by God's Holy Spirit, the same power that gave Peter the insight to recognize Christ's true office. Although Peter was given responsibilities of leadership, as connoted from the rock imagery or symbolism, he was not granted the post of 'vicar of Christ.' Peter would be considered first of the lively stones selected for His Temple. The apostles are indeed part of the foundation and Jesus Christ is the Corner Stone. Peter gets credit for being the first stone selected for the foundation that would also include us as part of the living stones. The 'keys of the kingdom' simply refers to the office of steward or caretaker to maintain the physical operations of the church, facilitating access to believers and protecting the sanctity from scoffers and detractors. Binding and loosing refers to powers of judgment, based on what God has already allowed through the apparent and manifest principles already revealed by the Scriptures.
