is always shown pointing up. The triangle was the only Trinitarian symbol used by the early church. It was used in the catacombs on grave markers.
1. TRIANGLE WITH CROSS – We often attribute the work of Salvation to Jesus and His death on the cross. However, the Trinity was and is fully involved with our salvation. Jesus died for our sins. God the Father raised Jesus from the dead giving us hope of the resurrection. The Holy Spirit convicts us and brings us to the point of repentance. Salvation is of the Triune God. This symbol does a wonderful job representing this.
2. TRIANGLE OF FISH – The fish stands for “Jesus Christ, God’s Son, Savior”. In this case three fish form a triangle, representing the Trinity. SEE ALSO: Animals: Fish.
3. TRIANGLE WITH OMICRON, OMEGA, NU – This triangle contains the Greek letters “Omicron”, “Omega”, and “Nu”. These letters represent the phrase spoken by God to Moses from the burning bush in Exodus 3:14 , εγω ειμι ο ων, meaning, "I am that I am". Keep in mind that this phrase was taken from the Septuagint, the Greek form of the Old Testament. The Old Testament was originally written in Hebrew.
4. TRIANGLE OF RABBITS – This is a symbol of the Triune God. The rabbits are of equal dimensions and form a triangle.
