This study guide is to be used with my book Understanding the Doctrine of Christ, according to Hebrews 5:12-14 & Hebrews 6:1-20. This guide has been laid out to be used in a classroom environment, using a very good Bible Concordance for scriptural references and either a KJV or NKJV Bible. It can be very easily used with my book which would explain in detail what is brought out here.
In the Christian faith, only a very few topics are as heart touching and have the ability to change a person inside out, as understanding the Doctrine of Christ. This doctrine, deeply rooted in Scripture, is not just a theological concept for scholars, it is the very heart of Christian identity, salvation, and spiritual maturity. To grip the Doctrine of Christ means to really understand who He is, what His purpose was here on Earth, and how we should respond.
“The Doctrine of Christ” is the “heart and soul” of Christianity, it tells us the “what and why” of what we must do for us to maintain our salvation.
What Is the Doctrine of Christ?
At its core, the Doctrine of Christ encompasses the total realm of how Christians are to live, worship, teach, preach, and maintain our salvation until our death. The Apostle John emphasized this in 2 John 1:9:
Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.
This verse shows us the gravity of understanding the Doctrine of Christ, it controls the legitimacy of one’s relationship with God. To misinterpret or disregard this policy means we are risking stepping outside the bounds of true Christian faith. (That’s right, we can lose our salvation.)
The Centrality of Christ in All Scripture
From Genesis to Revelation, Christ is that one single thread that ties all the teachings and Scriptures together. In Luke 24:27, Jesus Himself, after His resurrection, explained to His disciples the things concerning Himself “in all the Old Testament Scriptures.” The Old Testament points to His coming through prophecies, while the “New Testament” (Matthew, Mark, Luke, and John) reveals His life, death, and resurrection as the fulfillment of God’s redemptive plan. All other books of the “New Testament” deal with Salvation and being a disciple of Christ bearing good fruit.
So, understanding the Doctrine of Christ means reading and following its teachings in the light of Jesus and God. Thereby becoming the living Word that reveals the Savior of the world.
The Dual Nature of Christ
One of the most outstanding things about Jesus is his dual nature, as man and as God himself. This mystery, though beyond full human comprehension, is essential to Christian belief. John 1:14 says,
“And the Word was made flesh, and dwelt among us…”
Jesus, the eternal Word, took on human flesh. He did not lose His divinity when He became man, nor did He simply appear human, He was truly human. This union of divine and human nature in one person is known as the hypostatic union. Without understanding the Doctrine of Christ in this regard, believers risk falling into heresies that either deny His deity or His humanity, errors that the early church battled fiercely.
The Work of Christ: Redemption and Atonement
Another crucial aspect of understanding the Doctrine of Christ is recognizing His redemptive work. Jesus came not only to teach or to set a moral example, but to save sinners. His atoning sacrifice on the cross is the central act of God’s salvation plan. As Hebrews 9:22 says,
“…without shedding of blood is no remission [of sins].”
The shedding of His blood satisfied the justice of God and made it possible for humanity to be reconciled with Him. Through His resurrection, Jesus demonstrated victory over death and assured believers of eternal life. This doctrine is not academic; it is deeply personal. It is the hope of every Christian soul.
The Lordship and Return of Christ
Understanding the Doctrine of Christ also includes acknowledging His current and future roles. After His resurrection, Jesus ascended into heaven and now sits at the right hand of the Father, interceding for believers. He is Lord and King, reigning in power and glory. But His work is not yet finished.
Acts 1:11 promises that Christ will return:
“This same Jesus… shall so come in like manner as ye have seen him go into heaven.”
This future return, often referred to as the Second Coming, is a vital part of the doctrine. It is a call to readiness, holiness, and hopeful anticipation. Every Christian life is shaped by the reality that Christ will return to judge the living and the dead.
Why Understanding the Doctrine of Christ Matters
The implications of this doctrine are far-reaching. Firstly, it anchors the believer in truth. In a world of shifting moralities and deceptive philosophies, the unchanging nature of Christ’s doctrine serves as a compass. Secondly, it fuels worship. When we understand who Christ is and what He has done, we are moved to love, adore, and obey Him. Thirdly, it shapes Christian living. The more we grasp Christ’s humility, obedience, and sacrifice, the more we are inspired to follow in His footsteps.
Moreover, this doctrine guards the church against false teaching. As Paul warned in 2 Corinthians 11:4,
“For if he that cometh preacheth another Jesus, whom we have not preached… ye might well bear with him.”
A church that is not rooted in understanding the Doctrine of Christ is vulnerable to deception. Sound doctrine builds sound disciples.
Teaching and Living the Doctrine of Christ
The responsibility of every believer is not only to understand but also to teach and live this doctrine. This happens through Bible study, discipleship, and the practical application of Christ’s teachings in daily life. Paul instructed Timothy in 2 Timothy 1:13,
“Hold fast the form of sound words… in faith and love which is in Christ Jesus.”
We must hold fast. In our conversations, our ministry, our prayers, and our character, Christ should be evident.
Conclusion
Understanding the Doctrine of Christ is not a one-time study but a lifelong pursuit. It is both the foundation and the fuel of Christian faith. By immersing ourselves in this doctrine, we grow in intimacy with Jesus, deepen our theological discernment, and are equipped to live out the Gospel with integrity.
In times of spiritual confusion and compromise, let us return to the clear teachings of Scripture about Jesus Christ, our Savior, Lord, and coming King. For to know Him rightly is to know the truth that sets us free
