The triad or the Holy Trinity
A modern phonetic spelling of Trinity, referring to the Christian doctrine of the Father, Son, and Holy Spirit. It is derived from the Latin word 'trinitas', meaning 'threefold' or 'triad'. This specific spelling variation emerged in the late 20th century as a way to personalize the traditional virtue name.
