Comparison Between Heresy and Truth

As stated above, heretics are those who do not follow the laws of God—those who practice lawlessness. Among the many heresies in the world, let’s focus on the concept of Sunday service.

The Sabbath day—the seventh day, Saturday—is one of God’s commandments. All history books testify to this fact. For example, one of the many Catholic books, The Faith of Millions by Reverend John A. O’Brien, records as follows: "But since Saturday, not Sunday, is specified in the Bible, isn’t it curious that non-Catholics who profess to take their religion directly from the Bible and not from the Church, observe Sunday instead of Saturday? Yes, of course, it is inconsistent; but this change was made about fifteen centuries before Protestantism was born, and by that time the custom was universally observed. They have continued the custom, even though it rests upon the authority of the Catholic Church and not upon an explicit text in the Bible"(pp. 400-401). It is clear that Sunday service is a rule of men, not of God.

Among so many heresies, we have only explored the origin of Sunday service. The Sabbath day is God’s commandment, but Sunday service is a man-made teaching—heresy. Therefore, the Church of God, which follows the teachings of Second Coming Christ Ahnsahnghong, can be proven as the true Church because it keeps the Sabbath day.
