Are you not seeing the implication of the combination of the two images? What more clearly speaks to "liberation theology" than a such a perversion of the cross?
I know what they intended. But in reality, the depiction is pretty accurate — Christ crucified on an instrument of torture.
“Perversion of the cross” is quite the phrase. The cross is a shameful, horrible torture device. Yes, it’s also awesome, and glorious. But it was designed by the Romans to be gruesome. In a sense, God “perverted” the cross, by changing its original meaning as an object of defeat and hopelessness to a symbol of victory and hope.
