Tatian, the impressive intellect that he was, was not persuaded by historical evidence nor from the testimony of the church (though, as noted above, both are legitimate when appropriately utilized), but by the internal qualities of the Scriptures themselves.  There was something about the Scriptures that came alive to him.  How did he discern this?  As he indicates, “my soul being taught of God.”  Presumably this is a reference to the work of the Holy Spirit.

It probably comes as no surprise that the most common question I receive from both Christians and non-Christians is “How do I know the Bible is the Word of God?” And the reason this question is at the top of the list is not hard to determine.  The authority of the Bible is the foundation for everything that we believe as Christians.  It is the source of our doctrine and our ethics.  Thus, we need to be able to answer this question when asked.

Let me say from the outset that there is not just one answer to this question. I think there are many ways that Christians can come to know the Scriptures are from God. God can certainly use historical evidences to convince us of the truth of his Word (though it is important to understand the limitations of evidence).  And God can use the testimony of the church to convince us of the truth of his Word (I cover the details of this in Canon Revisited).

But, it is noteworthy that throughout the history of the church many Christians have ascertained the divine origins of the Bible in yet another way: its internal qualities. Apparently some Christians were persuaded of the Bible’s authority by reading it and observing its distinctive character and power.

Tatian is one such Christian. Tatian was a second-century Christian thinker, a disciple of Justin Martyr, and the author of an apologetic work known as Oration to the Greeks (c.165).  In this work, Tatian makes his case for the truth of Christianity.  During one section, he lays out his personal conversion story and recounts how he carefully examined all the pagan religious writings and found them incoherent, problematic, and, sometimes, downright evil.  But, then he happened to come across the Scriptures and began to read:

I was led to put my faith in these by the unpretending cast of the language, the inartificial character of the writers, the foreknowledge displayed of future events, the excellent quality of the precepts, and the declaration of the government of the universe as centered on one Being. And my soul being taught of God, I discern that the former class of [pagan] writings lead to condemnation, but that these [Scriptures] put an end to the slavery that is in the world (29).

This is a profound statement.
