Confucianism adheres to the teachings of Confucius. Buddhism adheres to the teachings of Buddha. Calvinism adheres to the teachings of John Calvin.
Christianity adheres to the teachings of Jesus Christ. I don’t like the phrase ‘true Christianity’, as it’s either Christianity, or it isn’t. It either follows the teachings of Jesus Christ, or it doesn’t.
Who is Jesus Christ?
Jesus was a real person who mankind considers so significant that we measure time from the event of his birth. I’m writing this in the year 2017, which means 2,017 years after the birth of Jesus.
Jesus claimed to be ‘the Christ’, that is, the khristos, the annointed (Matthew 16:20, Mark 14:61-62, John 4:25-26).
He claimed deity (John 8:56-58, Revelation 1:8: compare to Isaiah 48:12). He claimed to be not only sent from God, but God in the flesh. To borrow from Alcoholics Anonymous, he is “God as we understand him”.
The Bible calls Jesus Christ ‘the Word of God’ (Revelation 19:13). The Gospel of John begins by personifying Jesus Christ as ‘the Word’ (John 1:1-14).
The Bible is God’s message to man. Jesus personified that message. Therefore, Christians believe the Bible to be ‘the word of God’, thus the Bible IS Jesus Christ.
And Christianity is all about Jesus Christ.
It’s not “Churchianity”, as it doesn’t follow the teachings of “the church”.
It’s not even “Godianity” in the sense that God himself commands us to obey his will by believing on Jesus Christ (John 6:29).
It’s not about the sovereignty of God. It’s not what God CAN do; it’s what he DID do. And what he did was send Jesus Christ to be the Savior of the world.
Therefore, everything we do as obedient Christians flows from Christ, and points back to Christ.
If not, then it’s not Christianity.
