Theology, as seen by Archimandrite Vasileios, is by its very essence liturgical; it is not a philosophy or a system but the expression of the church's mystical life:

"The first Christians lived their theology totally and with the whole of their bodies, just as they are baptized with the whole of their body and soul into the new life...Thus their liturgical gatherings were an initiation into the mystery of theology...The mystery of theology was celebrated in their lives, and they attained to the knowledge which is eternal life."
Bishop Kallistos (Ware) states in his foreword:

[Hymn of Entry] offers nothing less than a fresh vision of theology, the church and the world, a vision that is both original and yet genuinely traditional. The quality that characterizes this remarkable book is above all a sense of wholeness. The unity of the divine and human in the incarnate Christ, the unity of heaven and earth in the Divine Liturgy, the unity between theology and spirituality, between theology and life - such are the author's master-themes.
