The Anti-Christ

Antichrist as defined by +Merriam Webster Dictionary is the Chief enemy of Christ who would reign at the end of time, first mentioned in the epistles of St. John. The idea of a mighty ruler who will appear at the end of time to fight against the forces of good was adapted from Judaism; the Jewish concept in turn had been influenced by Iranian and Babylonian myths of the battle of God and the devil at the end of time.

In the New Testament, the Antichrist is a tempter who works by signs and wonders and seeks divine honors. It was a potent concept in medieval Christianity that received the attention of many commentators including Adso of Montier-en-Der, whose work became the basic medieval treatise on the Antichrist.

An example of being an antichrist is forbidding anyone to marry and commanding his people or workers under him to abstain from eating meat on specific time of the season which they considered a "holy day".

1 Tim 4:1  Now the Spirit speaketh expressly, that in the latter times some will depart from the faith, giving heed to seducing spirits and doctrines of demons;

1 Tim 4:2 Speaking lies in hypocrisy, having their conscience seared with a hot iron;

1 Tim 4:3 Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving by them who believe and know the truth.

Forgetting this one verse in the Bible regarding serving God with one wife.

1 Tim 3:12 Let the deacons be the husbands of one wife, ruling their children, and their own houses well.  

Though there is a big difference in focus between the married and the unmarried.

1 Cor 7:27 Art thou bound unto a wife? seek not to be loosed. Art thou loosed from a wife? seek not a wife.

1 Cor 7:28 But and if thou marry, thou hast not sinned; and if a virgin marry, she hath not sinned. Nevertheless such shall have trouble in the flesh: but I spare you.

1 Cor 7:32  But I would have you without carefulness. He that is unmarried careth for the things that belong to the Lord, how he may please the Lord:

1 Cor 7:33 But he that is married careth for the things that are of the world, how he may please his wife.

1 Cor 7:34 There is difference also between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit: but she that is married careth for the things of the world, how she may please her husband.

Marriage therefore is a matter of choice, thus marrying is not a sin.

1 Cor 7:36 But if any man think that he behaveth himself uncomely toward his virgin, if she pass the flower of her age, and need so require, let him do what he will, he sinneth not: let them marry.

1 Cor 7:37 Nevertheless he that standeth stedfast in his heart, having no necessity, but hath power over his own will, and hath so decreed in his heart that he will keep his virgin, doeth well.

1 Cor 7:38 So then he that giveth her in marriage doeth well; but he that giveth her not in marriage doeth better.

To make a decree or a law forbidding anyone to marry (removing him from performing his spiritual duty if he opted to marry) is one of the doctrines of demons and therefore it's the  antichrist.
