Note
Parament featuring a Lamb, dove, hand on a triangle surrounded by the trefoil.
The parament uses the scriptural symbols for God the Father, God the Son and God the Holy Spirit.
God the Father is represented by the hand based upon the Old Testament references in Ezra 8:22, "...The hand of our God is upon all them for good that seek Him..." The New Testament also uses the figure of the hand as in I Peter 5:6, "Humble yourself therefore, under the mighty hand of God..."
God the Son is represented as the Lamb, one of the favorite and most frequently used symbols for Christ in all periods of Christian art. Many scriptural passages refer to Christ as the "Lamb of God." (John 1:29, I Corinthians 5:7, Revelation 5:13)
God the Holy Spirit as a dove is referred to in Luke 3:22, Matthew 3:16, Mark 1:10 and John 1:32.
The triangle was one of the earliest emblems to define the trinity and found in the catacombs.
The trefoil dates from 464AD as a symbol of three in one for the Trinity as used by St. Patrick to illustrate that doctrine.
