The term 'Symbol of Virtue' can be represented by the four-letter word 'HALO'. A HALO is a symbol of divine light and holiness, often depicted as a circle of light around the head of a saint or holy figure. It is also used to represent an aura of glory, innocence, and virtue. In Christianity, the HALO is associated with the Virgin Mary and Jesus Christ, and is seen as a sign of their holiness and purity.
