I don't know if you already heard about the one new man created in Christ Himself from two. Actually, I heard of it for the first time when I attended a Bible Exposition held in Cebu City by the Church of Christ (Filipino: Iglesia Ni Cristo). I never heard about it during my days in the Roman Catholic Church eventhough I actively performed my duties as the Sacristan Mayor of the Parish of San Agustin, Diocese of Surigao Del Sur. And this teaching is not just a teaching of the Ministers of the Church of Christ but it is the teaching of the Apostles as written on the Holy Bible.
However, in sharing this truth to you, I need to ask the Bible and let the Bible answer our questions because it is the Bible know this truth much.
To begin with, let us ask the Bible: Did the Apostle really teach that Christ created in Himself a one new man? Apostle Paul answer:
15 having abolished in His flesh the enmity, that is, the law of commandments contained in ordinances, so as to create in Himself one new man from the two, thus making peace, (Ephesians 2:15, NKJV)
According to him, a one new man was created in Christ Himself from the two. What is this ONE NEW MAN and what are the two referred to by Apostle Paul which composed the one new man? In Colossians 1:18, Apostle Paul's answer is recorded:
18 And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence. (Colossians 1:18, ibid)
The answer is: The two which are created into one new man are Christ and His Church and the one new man is Christ as head and the Church as Christ's body.
So, it is already clear that Christ really created a one new man. But what is the purpose of Christ, why he created this? Apostle Paul answered it already on the first verse that we used.
15 having abolished in His flesh the enmity, that is, the law of commandments contained in ordinances, so as to create in Himself one new man from the two, thus making peace, (Ephesians 2:15, NKJV)
According to him, it was done "to abolish the enmity, that is the law of commandment contained in ordinances and thus making peace".
What is the law that Apostle Paul referred to in which when the one new man was created peace does exist? The answer is recorded in Deuteronomy 25:16.
