The mystery of the holy Trinity is fundamental to christian faith. The pattern of the life of a Christian is derived from the pattern of the life of the trinity because we are Gods children and are created in his image. The understanding of the Trinity will deeply enlighten our minds especially in understanding the many facets of our faith. When a Christian refers to God he is referring to a communion of three distinct persons, In other words an indivisible union of three persons - the Father, Son and the Holy Spirt. The Father is eternal without a beginning, existed eternally and is without end. Father's knowledge, expression, words are also thus eternal and it is person whom we call the Son. Son is thus uncreated, begotten by the father. As light source and the light itself cannot be separated, father and son exists together in a self donating, all giving, relationship and this relationship or the love between them is the third distinct person whom we call the Holy Spirit.
