In the second epistle of John, the apostle John warned the elect lady about false teachers. God, through the apostle, gave all believers the distinctive mark of all false teachers, they abandon the doctrine of Jesus Christ.
7 For many deceivers have gone out into the world who do not confess Jesus Christ as coming in the flesh. This is a deceiver and an antichrist. 8 Look to yourselves, that we do not lose those things we worked for, but that we may receive a full reward. 9 Whoever transgresses and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the Father and the Son. 10 If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him; 11 for he who greets him shares in his evil deeds. 2 John 7-11
The doctrine of Christ entails all that God tells us about His Son in His Word the Bible. There are particular biblical doctrines about Jesus Christ that are under attack by false teachers. I want to focus on just three of those doctrines, since they engulf all of the other doctrines about Jesus Christ. The first of those three doctrines concerns Christ’s deity.
Simon Peter, a bondservant and apostle of Jesus Christ, To those who have obtained like precious faith with us by the righteousness of our God and Savior Jesus Christ:…2 Peter 1:1
…looking for the blessed hope and glorious appearing of our great God and Savior Jesus Christ. Titus 2:13
…of whom are the fathers and from whom, according to the flesh, Christ came, who is overall, the eternally blessed God. Amen. Romans 9:5
All cults such as the Jehovah’s Witnesses, Mormons, Disciples of Christ, etc. deny this basic doctrine regarding Jesus Christ, as do all who label themselves modernists. The second doctrine concerns Christ’s humanity.
1 Paul, a bondservant of Jesus Christ, called to be an apostle, separated to the gospel of God 2 which He promised before through His prophets in the Holy Scriptures, 3 concerning His son Jesus Christ our Lord, who was born of the seed of David according to the flesh, 4 and declared to be the Son of God with power according to the Spirit of holiness, by the resurrection from the dead. Romans 1:1-4
For there is one God and one Mediator between God and men, the Man Christ Jesus, who gave Himself a ransom for all, to be testified in due time,…2 Timothy 2:5
5 Let this mind be in you which was also in Christ Jesus,6 who, being in the form of God, did not consider it robbery to be equal with God, 7 but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. 8 And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross. 9 Therefore God also has highly exalted Him and given Him the name which is above every name, 10 that at the name of Jesus every knee should bow, of those in heaven, and of those on earth and of those under the earth, 11 and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. Philippians 2:5-11
I have spoken with those who didn’t believe that Jesus Christ had grandparents, as if Mary had no human lineage, although it is given in Luke chapter 3. If Jesus Christ didn’t truly descend from Adam, then He couldn’t be the last Adam and deal with our sin, nor could He represent us before the throne of God. The third and final doctrine deals with His redeeming work.
25 Therefore He is also able to save to the uttermost those who come to God through Him, since He always lives to make intercession for them. 26 For such a High Priest was fitting for us, who is holy, harmless, undefiled, separate from sinners, and has become higher than the heavens; 27 who does not need daily, as those high priests, to offer up sacrifices, first for His own sins and then for the people’s, for this He did once for all when He offered up Himself. 28 For the law appoints as high priests men who have weakness, but the word of the oath, which came after the law, appoints the Son who has been perfected forever. Hebrews 7:25-28
14 For the love of Christ compels us, because we judge this: that if One died for all, then all died; 15 and He died for all, that those who live should live no longer for themselves, but for Him Who died for them and rose again. 2 Corinthians 5:14-15
1 Moreover, brethren, I declare to you the gospel which I preached to you, which also you received and in which you stand, 2 by which also you are saved, if you hold fast that word which I preached to you-unless you believed in vain. 3 For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, 4 and that He was buried, and that He rose again the third day according to the Scriptures, 5 and that He was seen by Cephas, then by the twelve. 6 After that He was seen by over five hundred brethren at once, of whom the greater part remain to the present, but some have fallen asleep. 7 After that He was seen by James, then by all the apostles. 8 Then last of all He was seen by me also, as by one born out of due time. 9 For I am the least of the apostles, who am not worthy to be called an apostle, because I persecuted the church of God. 10 But by the grace of God I am what I am, and His grace toward me was not in vain; but I labored more abundantly than they all, yet not I, but the grace of God which was with me. 11 Therefore, whether it was I or they, so we preach and so you believed. 1 Corinthians 15:1-11
The Catholic church and any belief system that adds one’s own efforts to salvation contradicts this clear teaching in the Scriptures that Jesus Christ paid it all and we owe all to Him. Any works orientated teaching undermines the biblical teaching regarding what Christ Jesus has done for us, and damns all who hold to that spurious doctrine to hell.
And without controversy great is the mystery of godliness;
God was manifested in the flesh, Justified in the Spirit, Seen by angels, Preached among the Gentiles, Believed on in the world, Received up in glory. 1 Timothy 3:16
If we hold fast to what the Bible teaches about Jesus Christ, Who He is and what He has done for us, then we have both the Father and the Son and are assured of eternal life.
