This paper is devoted to the reconstruction of the ecclesiological doctrine of «Arian» bishop Maximinus – one of the opponents of St. Augustine. Comparison of the ecclesiological doctrine of Maximinus with the ideas of Augustine shows that they both were equally representatives of Latin theological tradition, which goes back to the legacy of St. Cyprian of Carthage. At the same time, Maximinus and Augustine give to this general tradition an entirely new and original interpretation: Augustine in the doctrine of the Church borders, Maximin in comparison of Trinity’s and the Church's unity.

Keywords:Maximinus, Augustine, ecclesiology, St. Cyprian of Carthage, Latin Arianism, Goths.
