Matthew 16:18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
Hebrews 10:25 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.
Jesus was the first one to use the word “Church” which literally means “the called out ones.” The Church consists of all those people who have been called out from the darkness, who have separated themselves from the world, to gather together unto the Lord Jesus Christ for worship, fellowship, and service. They have been called out of every kindred, tongue, tribe, and nation to be His Church and Body in then Earth (Rev. 7:9). For those who will say but we are the Church and don’t go to Church you may be enlightened by reading 1 Timothy 3:15 where Paul also calls the house of God (Grk. “oikos” – a dwelling place/house/home/temple) the Church and how to behave IN it.
The New Testament Church is still called out to assemble together. Assembling together, of course, is not the sum total of our Christianity or being a Christian but yes, we still go to Church or gather together as the Church. Modern day lies try to downplay the corporate gathering together. Some are rather feeble attempts to justify the desires of their flesh. Others have adapted down the truth of God’s Word to fit their personal choices.
The idea of people assembling together that is in the verse in Hebrews 10:25 is influenced by terms used for assembling in the OT Hebrew language and the NT Greek language. In the OT the word “Qahal” meant the called and assembled people of God. Qahal was often used to denote a gathering to judge and deliberate and in many contexts an assembly gathered to plan and execute war. As a congregation or company of people they were called out of their tents and dwelling places to assemble together.
The New Testament word used for “assembling yourselves,” is the Greek word “episunagogue” which meant a complete collection, especially a gathering together in one place of a group. In the Greek culture it came to mean the assembly of free citizens who were called out of their homes and places of business to assemble together to give consideration to matters of public interest. The Church of Jesus Christ is not only the called out ones but those called out to assemble together.
