Q. 1. What are the teachings of the Catholic Church on the Second Coming? How do they vary from the teachings of non-Catholics?
A. 1. On this subject the Catechism of the Catholic Church states: "Before Christ's second coming the Church must pass through a final trial that will shake the faith of many believers. The persecution that accompanies her pilgrimage on earth will unveil the "mystery of iniguity" in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth. The supreme religious deception is that the Antichrist, a pseudo-messianism by which man glorifies himself in place of God and of his Messiah come in the flesh." [C.C.C. # 675]
In other words, Jesus' final return shall be on the last day of the history of man, not before. His Second Coming shall be to implement the last Judgment of man. Regarding this day, the Holy Bible teaches, "No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father." [Mt. 24:36] "Stay awake! For you do not know on which day your Lord will come." [Mt. 24:42] These Bible passages affirm the Words of Jesus, "My Kingdom is not of this world." [Jn. 18:36]
Most Protestant denominations do not accept the Words of Jesus that His Kingdom is not of this world. As a result of their misinterpretation of the Holy Bible, they believe that Jesus shall return to rule on earth for 1,000 years, this return being called "The Second Coming." Many members of the Protestant Churches are waiting to rule with Jesus, not by Divine Appointment, but by self-appointment. They reason that they are all righteous and deserve such an honour. Those who embrace this falsehood will suffer spiritual death.
