Christian Wilhelm Franz Walch (25 December 1726 – 10 March 1784) was a protestant German theologian and professor of theology from Göttingen.
[1] His father Johann Georg Walch (1693–1775) was theologian, with theological position of moderate Lutheran orthodoxy.
He travelled with his brother to Netherlands, France, Italy, and Switzerland, making the acquaintance of the learned men of each country.
At the end of 1766, he became the first professor of the theological faculty and in the Society of the sciences, philological-historical class, in Göttingen.
In this work he defined a heresy on the one hand as a branch of Christianity and on the other as one in fundamental error.
