What is the Heresy?

Many people have a misunderstanding of what heresy is nowadays. Once they find a man practicing doctrines different from their own, they likely think he belongs to a heresy. We are not supposed to judge others by our own thoughts, social standards, or popular opinions. We must understand what heresy is through the Bible.

2 Pe 2:1-3 They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them.
 
The main characteristics of heresy are as follows;
1. It results in destruction.
2. It brings the way of truth into disrepute.
3. It follows man-made teachings, not the teachings of the Bible.
4. It opposes God through the teachings of false prophets.
5. It never leads to salvation.
   
What does the Bible say about heresy? It does not follow teachings of the Bible, but man-made teachings instead.  

1. Heresy does not keep the Sabbath in the Bible.The Biblical Sabbath is Saturday. Every church must worship God on Saturday, not on Sunday. there are some proof.
• "… The Scriptures enforce the religious observance of Saturday" (The Faith of Our Fathers, pp. 72～73).
• "The first day of the week [Sunday] was proclaimed as a day of rest and of worship … In 321 A.D. Constantine …" (The Story of the Christian Church, pp. 60～61).
Jesus also testifies the Sabbath day is His custom in the Bible. Jesus kept the Sabbath day as an example so that we should do as He did.
Lk 4:16 On the Sabbath day he went into the synagogue, as was his custom
Jn 13:15 I [Jesus] have set you an example that you should do as I have done for you.

2. Heresy does not celebrate the Passover in the Bible.
The Passover is God's truth that gives us the forgiveness of sins and judges all other gods. Those who do not keep it will be cut off from God's people on the last day.
Mt 26:17-28 This is my blood of the covenant, which is poured out for many for the forgiveness of sins.
Jn 6:53 Whoever eats my flesh and drinks my blood has eternal life.
Ex 12:11-12 On the same night … I will bring judgement on all the gods of Egypt.
Nu 9:13 If a man fails who is ceremonially clean and not on a journey fails to celebrate the Passover, that person must be cut off from his people.

3. Most contemporary Christians keep Christmas [Dec. 25th] as Jesus' birthday. In fact, Christmas is one of many pagan festivals not in the Bible.
• "The Christian church took over many pagan ideas and images. From sun-worship, for example, came the celebration of Christ's birth on the twenty-fifth of December, the birthday of the Sun” (A LION HANDBOOK / THE HISTORY OF CHRISTIANITY, p. 141).
• "December 25―this was the date of a pagan festival in Rome, chosen in A.D. 274 by the emperor Aurelian as the birthday of the unconquered sun (natalis solis invicti), which at the winter solstice begins again to show an increase of light" (ENCYCLOPAEDIA BRITANNICA, p. 704).

4. Heresy reveres a cross, an idol, from pagan Rome. It is a type of execution tool used for crucifying brutal criminals, and is not the symbol of Jesus Christ. 
 

The standard of heresy is the bible only. However most of christians don't follow it. 2,000 years ago, Jesus and His Church of God were wrongfully accused as a Nazarene sect, one of the heresies (Ac 24:5). However, most people acknowledge Jesus as their Christ. Likewise, the whole world will acknowledge Christ Ahnsahnghong and the Church of God in the end. Come to the Church of God and receive salvation.
