Is Organized Religion Anti-Christ?
No, anti-Christ is the religion that confesses to be against Christ. What is the meaning of the word "Christ?" "Christ" is originally from the Greek and it means the anointed one of the Lord aka the Messiah. Now, if you read Prophet Habakkuk 3:13, "The Lord goes forth to save His People; to save His anointed one," aka Christ, the Messiah. As you can see, Theologically, Prophet Habakkuk was talking about God's People aka Israel as the anointed one of the Lord. Obviously, the Messiah cannot be an individual but Israel the People. The individual is born, lives his span of life and dies. Are we to expect a new Messiah in every generation? Obviously not. The Messiah cannot die but to remain as a People before the Lord forever. (Jer. 31:35-37)
In conclusion, if you read I John 2:18,19, the antichrists are supposed to rise from the ranks of Christianity itself. Evidence of the fact is, that Paul, the founder of Christianity has demonstrated to be the leader of all antichrists through the means of the Pauline policy of Replacement Theology.
