A Holy Trinity icon, famously Andrei Rublev's "Trinity," symbolizes the three-in-one God (Father, Son, Holy Spirit) as three angelic figures sharing a meal, representing divine love, unity, and peace. With symbolic elements like colors (blue for divinity, red for humanity), backgrounds (home, tree, mountain), and gestures illustrating their relationships and roles in salvation, inviting viewers into this communion. It's a window into heaven, showing God's eternal life, mutual love, and the path to salvation through Christ's sacrifice.
