Trinity
Shield Of The Trinity

White is the color used for the first Sunday of Trinity.  So this banner is made on a white upholstery material; white originates in undiminished light and therefore implies the eternal presence of God.
Nowhere in the Bible do we find the word TRINITY mentioned, but in (Genesis 1:26) God said, "Now we will make humans, and they will be like us", and in (Matthew 3:16-17) verse 16 says "So Jesus was baptized and as soon as he came out of the water, the sky opened, and he saw the Spirit of God coming down on Him like a Dove", verse 17 says then a voice from heaven said, "this is my own dear Son, and I am pleased with Him," so here we have the Father, the Son, and the Holy Spirit mentioned together...thus the Trinity.
The Shield of the Trinity is made os a green suede like material.  At the top and to the left is a circle enclosing the word SON and to the bottom a circle enclosing the word HOLY SPIRIT, in the center is the word GOD.  The unity of the Godhead is expressed by using the word "IS" on each line, starting from the corners and leading to GOD, thus you read "the FATHER is GOD; the SON is GOD; the HOLY SPIRIT is GOD.  The three persons of the God head are clearly distinguished by the words "IS NOT."

Trinity - Shield Of The Trinity
Translating this part of the symbol we read, "the FATHER is not the SON; the SON is not the HOLY SPIRIT; the HOLY SPIRIT is not the FATHER.  The Shield is trimmed with gold metallic braiding and outlined with a green cording.
The symbol for the FATHER is the Hand from a cloud.  The hand appearing in various farms, is probably the most outstanding scripture symbol of GOD and FATHER (Exodus 15:16) (Psalm 48:10).
The symbol for the SON is the LAMB, standing with the banner of Victory, (No Longer Wounded) suggesting the victorious nature of JESUS' sacrifice.
The symbol for the HOLY SPIRIT is the Dove, the basis for this symbol is entirely scriptural and may be found in the story of the baptism of CHRIST, (Matthew 3:13-17) (Mark 1:9-11) (Luke 3:21-22) and (John 1 13-14) the nimbus on the Lamb and Dove suggest the Glory of GOD.
These symbols are made from various kinds of metallic material and are all trimmed with yarn or metallic cording.
There are many symbols for the TRINITY, three intertwining circles, the Triquetra and three circles or three fish in a circle.  The triangle, the shamrock, the fleur-de-lis (sometimes used on the ends of the cross).  All suggest the Trinity.
This banner was made of white upholstery material, the shield was made of green because the color for the Trinity season is green.  The banner is finished with heavy green fringe.
