The Church

Matthew 16:13–18 NKJV

13 When Jesus came into the region of Caesarea Philippi, He asked His disciples, saying, “Who do men say that I, the Son of Man, am?” 14 So they said, “Some say John the Baptist, some Elijah, and others Jeremiah or one of the prophets.” 15 He said to them, “But who do you say that I am?” 16 Simon Peter answered and said, “You are the Christ, the Son of the living God.” 17 Jesus answered and said to him, “Blessed are you, Simon Bar-Jonah, for flesh and blood has not revealed this to you, but My Father who is in heaven. 18 And I also say to you that you are Peter, and on this rock I will build My church, and the gates of Hades shall not prevail against it.

Church: (Olive Tree Enhanced Strong's Dictionary) those who anywhere, in a city, village, constitute such a company and are united into one body, the whole body of Christians scattered throughout the earth

Acts 20:26–30 NKJV

26 Therefore I testify to you this day that I am innocent of the blood of all men. 27 For I have not shunned to declare to you the whole counsel of God. 28 Therefore take heed to yourselves and to all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood. 29 For I know this, that after my departure savage wolves will come in among you, not sparing the flock. 30 Also from among yourselves men will rise up, speaking perverse things, to draw away the disciples after themselves.

Acts Chapter 20

After my departure. His presence had been the means of guarding the church, and preserving it from these dangers. Now that the founder and guide of the church was to be removed, they would be exposed to dissensions and dangers.

Grievous wolves. Heavy (βαρεῖς), strong, mighty, dangerous wolves—so strong that the feeble flock would not be able to resist them. The term wolves is used to denote the enemies of the flock—false, and hypocritical, and dangerous teachers

Ephesians 5:25–30 NKJV

25 Husbands, love your wives, just as Christ also loved the church and gave Himself for her, 26 that He might sanctify and cleanse her with the washing of water by the word, 27 that He might present her to Himself a glorious church, not having spot or wrinkle or any such thing, but that she should be holy and without blemish. 28 So husbands ought to love their own wives as their own bodies; he who loves his wife loves himself. 29 For no one ever hated his own flesh, but nourishes and cherishes it, just as the Lord does the church. 30 For we are members of His body, of His flesh and of His bones.
