Salvation is a very Christian idea, which is the reason why Jesus Christ came down to earth. He came not to give mankind knowledge by salvation. The ultimate objective of every Christian is salvation and theosis. Therefore, we all need to aspire to this. However, what is salvation. Below are two quotes, the first by Christos Yannaras and the second one by Fr. George Florovsky. These two quotes explain this term, which in many respects is alien towards the way of life we have today, in respect to our modern, digital and capitalistic way of life.
“In our days, a mistaken religious upbringing has led many people to consider the Church as a means or instrument to ensure individual salvation for each of us – and when they talk of “salvation” they mean an unlimited kind of survival after death in some “other” world. But in reality the Church entrusts to everyone the enormous honour to be responsible for the salvation of the whole world, of this world whose flesh is our flesh and whose life is our life. And salvation for the Church is the liberation of life from corruption and death, the transformation of survival into existential fullness, the sharing of the created in the mode of life of the uncreated”.
“Salvation is more than forgiveness. It is a genuine renewal of man. And this renewal is effected not by the discharge, or release, of certain natural energies implied in man’s own creaturely being, but by the “energies” of God Himself, who thereby encounters and encompasses man and admits him into communion with Himself”.
