“it`s impossible to be saved in the world and only monastic life could lead to sanctity”. Of course we all look on situation from our own site but I cannot agree with this statement totally.
This monk is very, very seriously mistaken. Salvation is indeed possible to those living "in the world", as shown by the multitude of single and married laymen who have been proclaimed as saints. The Orthodox wedding service also has much to say about marriage and its part in the salvation of the couple.
I would only add that any such monk has succumbed to the sin of pride and is dangerously wrapped up in his own hubris.
Wasn't the idea of the superiority of celibacy and the denigration of marriage and worldly life declared a heresy pretty early on?
Most early Church Fathers I've read thought monasticism superior. That everyone needs to quote the same 2 passages in St. John Chrysostom to find an example of a Father who didn't think this is telling. Now, at Gangra
(and in general) marriage was defended, and these canons were ecumenicalized at Trullo. As for marriage vs. monasticism, it all depends on where the line is drawn. At the risk of oversimplifying, there are three general positions:
1) Monasticism is superior or mandatory; marriage and sex are evil or to be denigrated. This is heresy.
2) Monasticism is superior; marriage, while inferior, is nonetheless a sacrament and perfectly acceptable. This was the position of most of the Fathers I've read.
3) Monasticism and marriage are equal if different paths to salvation. This is the position of most modern Orthodox.
