From: Letters on the Spiritual Life
When the Lord was taken down from the Cross, the Cross remained on Golgotha, and then it was thrown into the pit that was in that place, where this instrument of execution was usually thrown, together with other refuse. Soon Jerusalem was razed and all of its edifices were leveled to the ground. The pit containing the Cross of Christ was also filled over. When the pagans rebuilt the city (the Jews were forbidden to come near the place where it was), it happened that on the place where the Cross of Christ was hidden, they placed an idol of Venus, the pagan Goddess of fornication and all manner of lusts. This is what the enemy suggested to them. This is how it is with our inner cross. When the enemy destroys the spiritual order in the soul, this is our mental Jerusalem, and then the spiritual cross is thrown down from the Golgotha of the heart and is covered over with the garbage of the affections and lusts. Lustful self-pleasure then rises like a tower over all our inner peace, and everything in us bows down to it and fulfills its commands until grace shines upon us, inspiring us to cast down the idol and lift up the cross of self-crucifixion.
