Gnostic - Theistic Fatalism
The Gospel of Truth is one of the Gnostic texts from the New Testament apocrypha found in the Nag Hammadi codices. The Nag Hammadi library was discovered in Egypt in 1945. Among the varied collection of works classified as gnostic was a series of writings which could be associated with Valentinus, particularly the Coptic text called the Gospel of Truth which bears the same title reported by Irenaeus as belonging to a text by Valentinus.
The Gospel of Truth - The Fathers Paradise

“Now the Father rests in his will, and is pleased with it. Nothing happens without him, nor does anything happen without the will of the Father, but his will is incomprehensible. His trace is the will, and no one can know him, nor does he exist for people to scrutinize so that they might grasp him, but when he wills, what he wills is this – even if the sight doesn’t please them in any way before God – the will of the Father, because he knows the beginning of all of them, and their end, for in the end he’ll greet them directly. Now the end is receiving knowledge of the one who’s hidden; this is the Father”
Now let’s look how nearly identical the writings of Calvin match this Gnostic Theistic Fatalism. Also note how clearly the Gnostics taught that “receiving knowledge of the one who’s hidden; this is the Father”.
John Calvin [a.d. 1509-1564]
Institutes of the Christian Religion - Chapter 6 - Section 1

To this first knowledge was afterwards added the more intimate knowledge which alone quickens dead souls, and by which God is known not only as the Creator of the worlds and the sole author and disposer of all events, but also as a Redeemer, in the person of the Mediator.
Calvin teaches that it is this knowledge that is added by which God is known.
