St. Symeon is not a systematized theologian (and therefore not scholastic) but rather a theologian using his heart. He is a mystic! He uses seeing and feeling words to convey awareness of God beyond what the mind is capable of grasping on it’s own.
He feels that all Christians, according to the teaching of Jesus Christ as recorded in the New Testament, should directly experience the grace and indwelling of the Holy Trinity.
The important question that St. Symeon poses to his listeners (these are sermons after all) is not whether the Holy Spirit lives within them but whether they are consciously aware of the presence within through continued penitential conversion. – from the Introduction to The Discourses.
So let’s have the really good question… Are you consciously aware that the Holy Spirit lives in you through continued penitential conversion?
St. Symeon is not teaching a moral or philosophical system but a therapeutic model of people being healed by Jesus Christ. He is right in line with what has been taught everywhere at all times in the Orthodox Church. The Church is not a religion. It is the Body of Christ, the Church, the Kingdom of God and, as such, we see ascesis (exercises) and theoria (vision / contemplation of God) are the two main sermon themes. Ascesis and theoria for the healing of soul and body by uniting us to the Uncreated energies of the Holy Trinity.
