Danielle Bregoli got a tattoo on the back of her left forearm in August 2018 depicting the face of a cherub statue.
The cross on the forehead of the cherub is a symbol of allegiance to God, inspired by several passages of the Christian Bible. When God wants to destroy the city of Judah in Ezekiel 9:4, God says to put a cross on the forehead of people who are saddened by the abominations committed there so that they will be spared. In Revelation 7:3 the angels put a seal on the foreheads of servants of God.
Statues of Christian figures never include a cross on the forehead, however there are many historical examples of vandalism by early Christians who carved crosses into ancient Greek and Roman statues to “Christianize” them.
