The sufficiency of the Scriptures is for the most part under sharp attack. If indeed it is inspired, God-breathed, and infallible (2 Timothy 3: 16), then it should be embraced as it claims. 

In post-mordern culture, experience, signs, miracles and wonders are substituted for the authority of the Bible. Ecumenism plays very well at the backdrop of this issue; no wonder unbelief is common even among the evangelicals. With many teachings arising each now and then, it is no surprise the authority of the Scriptures is being watered down. 

Apparently, we are not the first generation grappling with such a matter. In the first century, when the apostles were still alive, heresies were commonplace. This is evident as we go through the Epistles. Jude, the brother of James, urged the believers to contend for the faith once entrusted to the saints (Jude 3). What this means is that some had veered off the same faith delivered through the law and the prophets, and later confirmed through the gospel (Luke 16: 16). Paul noted this faith which they labored to preach through the word of mouth, with the heart believing (Romans 10: 8-10). That is why he confronted the Galatians when he had heard that they were compromising the true gospel (Galatians 1: 6, 7). His following words though harsh, conveys the oneness of the gospel which seems to stress the same thing as the Epistle of Jude. 

The testimony of the Holy Spirit during the day of Pentecost was such resounding to the extent that even a testimony given by an angel would be rendered faulty accompanied by a double curse! (Galatians 1: 8-9). 

By now, it is not hard to see how easily something pure can be defiled. In a culture where “your way works for you and not me”, it is almost futile trying to convince someone that Christ is the only way (John 14: 6). The basis for objectivity is destroyed once we allow subjectivity pervade the fabric of our belief system. Yet when subjectivism is expressed in its fullest form, nihilism is bound to arise. 

Even though today the world hosts six major religions including Atheism , much hasn’t changed compared to the ancient times. Hinduism would be a replica of polytheistic nations such as Greece (Acts 17:16-32). Islam would be a replica of Judaism where the deity of Christ is denied (John 8) . Atheism would be a replica of those regarded as fools (Psalms 14 & 53).

Just to backtrack and go straight to the gist of this topic; the Word (revealed through the Scriptures) was always with God, was God, (John 1: 1) and indeed became flesh (John 1: 14). In his first Epistle, John reemphasized this truth as the only gospel entrusted to the followers of Christ and not any other (1 John 4: 2, 3).
