So, how do we evangelize and "engage the culture"? I think the answer is this: There is no Orthodox service for the baptism of a "culture". There is only one baptism: of persons, and one at a time. The "Church" does not engage cultures, saints encounter people. When enough people live as saints and enough persons are baptized because of those encounters, cultures change. (But even so, cultural relevance or baptism of a culture is still not the goal, the salvation of the person is. An "Orthodox culture" guarantees nothing personally to anyone. Modern Greece with the highest promiscuity and abortion rate in Europe along with its abysmal percentage of church attendance of baptized Orthodox at least anecdotally indicates that having an "Orthodox culture" is no guarantee that "Orthodoxy" is influential culturally or personally).
If the Church is to be relevant, the Church has to be relevant to each member, they must engage its agenda to make one a saint. And its members as saints are personally relevant to people. It is impossible for the Church to be relevant to "the world" apart from its creation of saints within it. Putting up websites, hanging banners or doing programs to attract a demographic and then working "the plan" on those they attract is a cheap back up because we have few saints among us who walk in the world as salt and light. Madison Avenue and market research replace the "fragrant aroma of Christ" (II Cor. 2:14ff), the beauty of "love unfeigned" (Rom. 12:9) in the image of Christ to attract people to Faith.
A phony, insincere, arrogant, base, impure, irreverent, insulting, impatient, selfish, egoistical, narcissistic, angry, harsh, judgmental, rude and impious person is irrelevant to everyone. The Saint needs no banner, no website, no technique, no contrived marketing image because he is in the image of Christ and thus relevant to each person he encounters, regardless of culture or demographic.
If Dimitru Staniloae is even close, what the Church needs is more saints to go into all the world, not more marketing plans to get people to come to the Church.
