Shall You Sin Aganst God and His People?

Yes, it is a commandment that you attend public worship on Sunday. The requirements for worship,

entering into the Holy of Holies by the blood of Jesus, are set forth in Hebrews 10:

19 Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus,

20 By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;
21 And having an high priest over the house of God;
22 Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil 

conscience, and our bodies washed with pure water.
23 Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;)
24 And let us consider one another to provoke unto love and to good works:
25 Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: 

and so much the more, as ye see the day approaching.

This passage follows the doctrine that the old has passed away--or will shortly by the destruction of the 

temple and the end of the Mosaic order. What then is left is the new and living way described briefly in these 

verses, but expanded more at length in the pastoral epistles and other writings of the New Testament.

What the writer of Hebrews has described in brief form is the substance of the Ten Commandments: To 

love God with all our hearts, souls, mind and strength and to serve no other; to do good works before men 

and to let our light shine, loving the people of God and rejoicing in the church that He purchased with His 

blood.

We still have a priest and a house of God, described in Eph.4 and 1 Timothy 3:15. Do not sin against God 

and His people. To say there is no church is to say there is no Christ and no Christianity.

Verse 32 warns that despising the church will bring greater judgment than despising Moses in the days of the 

law, for that would involve trampling on the blood of Christ..

Yes, it is a great sin to forsake and despise the weekly gathering of the people of God, especially if it is
accompanied by self-righteous and wicked judgment upon the ministry and the people of God.
