The great deceiver has many heresies prepared to fit the different tastes of those he wants to ruin. His plan is to bring into the church insincere, unconverted people who will encourage doubt and unbelief. Many who have no real faith in God agree to a few principles of truth and pass as Christians, and in this way they are able to introduce error as Bible doctrine. Satan knows that the truth, received in love, sanctifies the life. So he tries to substitute false theories, fables, another gospel. From the beginning, servants of God have opposed false teachers, not because they considered them vicious people, but because they taught falsehoods that were fatal to the spiritual life. Elijah, Jeremiah, Paul, firmly opposed those who were turning others from the Word of God. The liberal mind-set that thinks correct faith is not important found no welcome with these holy defenders of truth. LF 213.5
The vague and inventive interpretations of Scripture and the conflicting religious theories in the Christian world are the work of our great adversary to confuse minds. The discord and division among the churches come mostly from twisting the Scriptures to support a favorite theory. LF 214.1
In order to prove false doctrines, some take hold of passages of Scripture separated from the context. They quote half a verse as proving their point, when the remaining portion shows that the meaning is the opposite. With the wily deceit of the serpent they take their position behind unrelated statements intended to please carnal desires. Others turn to figures and symbols, interpret them to suit their ideas with little care for the testimony of Scripture as its own interpreter, and then present their erratic thoughts as the teachings of the Bible.
