Priest Alexander Kovalev
In the broader sense given to that sin in the Holy Scriptures, it is the idolatrous attachment to the visible world… Fornication means giving your heart not to one who is worthy of love; it means instead of directing your will to the one thing needful, to pure, holy love for a person, for people, and for God, you vaporize it, disperse it anarchically, in all different directions, so that it serves all idols, all desires, and every impulse.
