So, who’s “normal” from an Orthodox perspective?
“If you want to see this clearly, read the divine service of the Holy Baptism, and the divine service of Holy Chrism held in the Patriarchate of Constantinople on Holy Thursday, or read the service for the consecration of Church sanctuaries. There we will see what it means to be a ‘Temple of the Holy Spirit’. There we will see who is illumined.” We actually say something like that sometimes in common language usage: “This is a bright young man”, for example.
The question is: Who is really bright, illumined, after all?
Only our Liturgical Tradition can lead us to the answer of this question and make us really understand. The Church (the Orthodox is always considered as such) has no ideas, but possesses a therapeutic method, offers a medical treatment. And, when someone becomes healthy, his/her healthy state is observable by a number of specific things and points. The same is obvious on a sick person, too.
The spiritually healthy person is the one who is illumined, the one who has become a Temple of the Holy Spirit. A cured and spiritual person has the ability to discern who is healthy and who is ill, by just looking at the other people.
