His Name is Jesus Christ
            It was the name given from heaven for the Son of the virgin, St. Mary, without the seed of man, by the Holy Spirit, who was born in Bethlehem (Luke 1:30, 31). The name “Jesus” is the Greek for the Hebrew name “Joshua” which means, “God saves,” for He will save his people from their sins (Matthew 1:21). So, this name declared His main objective of His incarnation among us, i.e. our salvation.
The word “Christ” literally means “The Anointed One” as it was prophesied by the prophet Isaiah in (Isa 61:1). This name was given to whoever was anointed with the holy oil by the prophets in the Old Testament, whether the person was a priest, a king, or a prophet (Exodus 40:13-15; Leviticus 8:12; 1Samuel 16:13; 24:6; 1King 19:16; Psalms 105:15). It refers to Christ’s mission as a King, Priest, and Prophet. He is the only one in whom these three occupations exist at the same time; and was anointed by God the Father (Hebrew 1:9). He is the “Messiah,” not just the Anointed One, as they used to call Him in the Old Testament, and the Jews were waiting for His coming (John 4:25, 26-29, 42). St. John in His Gospel proves that Jesus is the Christ, the core of all prophecies and symbols of the Old Testament (John 20:30, 31). Therefore, the name “Jesus” refers to His Humanity, while the name “Christ” refers to His Divinity. The Apostles, in their preaching and writings, used to call Him “Jesus Christ our Lord,” and not just “Jesus” (Romans 1:3; 16:27; 2Corinthians 1:1; 13:14). St. Peter declared the power of Jesus’ name by saying to Jews, “Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved” (Act 4:12); proving that the lame was healed by the power of this name, “And His name, through faith in His name, has made this man strong, whom you see and know” (Act3:16; cf. 4:10).  
Emmanuel
            Christ, in His birth, was called “Emmanuel,” as Isaiah prophesied and said, “Behold, the virgin shall conceive and bear a Son, and shall call His name Emmanuel” (Isa 7:14). This prophecy was referenced by St. Matthew (Mat 1:22, 23). Emmanuel, meaning God is with us, is with us all the time, not just in His eternal kingdom (John 17:24), but on earth too, as He says, “Lo, I am with you always, even to the end of the age” (Matthew 28:20)… Not just with us, but He dwells in us, as He says, “If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him” (John 14:23). And He is in our midst, “For where two or three are gathered together in My name, I am there in the midst of them” (Matthew 18:20). He even abides in us, and we in Him, “He who eats My flesh and drinks My blood abides in Me, and I in him” (Jn. 6:56). His presence with us, and in us, at all ages till the end proves His unlimited divinity.
The Logos
            St. John, in his Gospel, repeatedly refers to Jesus as the “Word” or “Logos in Greek (John 1:1-14), i.e. Christ is the “Word of God.” The term is most appropriate. Unless a man speaks his mind in a word we cannot know him. As words express our inner thoughts, so Christ, the Word of God, communicates the thoughts of God to us. Through Him, we knew the Father, as He says, “He who has seen Me has seen the Father” (John 14:9; cf. 1:18). He is the uttering intellect of God, the creating Word, the divine Wisdom, or the rational utterance of God. The intellect or wisdom of God existed in God since eternity. About Him, St. Paul said that the Father “has in these last days spoken to us by His Son… through whom also He made the worlds” (Hebrew 1:2).
The Only Begotten Son
             He was born from the Father, not through a mother, before all ages; and was born from a mother, without father, in the fullness of time. This expression is meant to distinguish His son-ship to the Father from ours; for He alone is the Son of God of His same nature, essence, and divinity; who was born from the Father before all ages. It is a Biblical expression mentioned many times (John 1:18; 3:16, 18; 1John 4:9, 14). We are called sons of God, even though we don’t have God’s nature. God called us His children out of His great love to His believers (1John 3:1), as St. John says, “But as many as received Him, to them He gave the right to become Children of God, to those who believe in Him” (John 1:12). We are His children by adoption (Galatians 4:4, 5; Romans 8:23). Therefore He is called also “The Son” (John 3:35, 36; 5:20, 22, 23); and the divinity of the Son is also clear (John 8:36; 1John 5:12; Luke 10:22).
For proving His divinity, Jesus is called clearly the “Son of God” as it is repeatedly mentioned in the Gospels (Mark 1:1; 1:11; 15:39; 3:11). It is St. Peter’s declaration of faith, for which Christ praised St. Peter (Matthew 16:13-18). He was begotten of the Father before all ages. He said to the Jews, “Before Abraham was I am” (John 8:56), meaning that regarding His divinity, He existed before Abraham. And through it is said that He is the Son of Abraham, the Son of David, with regard to His humanity, He is the Root of Abraham and David, with regard to His divinity; therefore He said, “I, Jesus… I am the Root and the Offspring of David” (Rev 22:16). He also said in His soliloquy with the Father, “And now, O Father, glorify Me together with You, with the glory which I had with You before the world was” (John 17:5). His being before the creation of the world is obvious because “the world was made through Him” (John 1:10; cf. 1:3).  
The Lord
            The word “Lord” also means “Master” and “God” (Matthew 7:22, 23; 25:37,44; John 20:28; Acts 7:59; 1Corenthians 8:6). This word was used throughout the Old Testament for God (Deut 10:17). It is the title the early church deliberately gave to Jesus to express that He is the absolute and undisputed Creator (Romans 10:9; 1Corenthians 12:3; Colossians 12:6). He is the Master and we are His servants. He is not only “the Lord” but “the Lord of lords” and “God of gods” (Revelations 17:4; 19:16).
            Christ said about Himself that He is the Lord of the Sabbath (Matthew 12:8; Mark 2:28; Luke 6:5). This means that He is the God of the Sabbath and the founder of the Law. As we all know that the commandment of keeping the Sabbath was given the Lord (Exodus 20:8-11), and the reason behind keeping the Sabbath goes back to the story of Creation (Genesis 2:1-3). Therefore, Christ, who is the Lord of the Sabbath, was existing before these events, and has the authority to change the Law or to clarify the exact meaning behind the commandments. The Jews, for example, learned to keep the Sabbath literally (John 5:10; 9:16; Matthew 12:1, 2, 9-15; Luke 13:10-17; 14:1-6), but He taught them the Spiritual meaning of keeping the Sabbath (Mark 2:23-28; Matthew 12:1-8; John 7:22-24). wiscopts.net/spiritual-library/spiritual/133
