The term 'Symbol of Sainthood' can be represented by the word 'HALO', which is a four letter word. A HALO is a symbol of holiness, righteousness, and divine power, and is often depicted in religious art as a glowing circle around the head of a saint or holy figure. It is also used to represent the presence of an angel or divine being. In Christianity, the HALO is a sign of sainthood and is often used to represent the spiritual nature of a person.
