Let us consider the way in which the psalmist speaks about the divinity of Christ. He does not try to coerce us into belief. What we believe is a matter of indifference to him. He simply announces a fact: the one addressed in the psalm is a priest, a king, and my God (cf Ps 145:1). There is no need of any further explanation. If you so wish, believe in Him; if not, don’t believe. In either case, He remains the Eternal King, seated upon His throne. If you so wish, offer Him your heart, for we encounter God in faith, in the spacious freedom of the heart. The Lord does not approach us in order to sway us with arguments and theories. He approaches us in order to enter our hearts.
(Archim. Aimilianos of Simonopetra, Psalms and the Life of Faith
