For the last hundred years in particular, the world has seemed to be intent on speeding towards this self-inflicted end in a series of suicidal acts of hatred of God, man and self. However, we know that this rush to embrace spiritual and physical death is not inevitable. It can be slowed, stopped and even reversed. However, in order to do any of this, all who are willing must first be baptised into the Orthodox Church in the Name of the Holy Trinity and strive to live by Her. And if this is to happen, a number of very basic missionary principles must be followed. These principles are inherent in the very definition and nature of the Church as One, Holy, Catholic and Apostolic.
