Dr. Matti Petteri Koppinen (b. 21 January 1976 in Turku, Old Finland) is a Uralica pastor, professor, religious authority figure, theologian, politician, and author. Easily one of the most recognisable figures in Uralica, he is often called "the Calvin of the East" because of his commitment to having a good theological foundation for his people, but also because of the fact that he is considered the founder of the Uralican Evangelical Baptist Church and on of the founding fathers of Uralica.
