Relativism, or the lack of belief in any universal truth, is very much a part of mainstream thinking in our culture.
I think that this lack of truth, lack of purpose or meaning in people's lives, is sad and unfortunate, and leaves people living their lives in darkness.
For there is Truth. There is purpose. There is meaning to human life.
Jesus says "whoever sees me sees him who sent me. I have come as light into the world, so that everyone who believes in me should not remain in the darkness."
Jesus reveals to us that we are made in the divine image, that God's Life is in us, and that we are One in the Loving movement of God.
The more a person comes to know Jesus, the more they come to know who they really are. They come into the Light of what Life is. They come to know the Truth.
Today is the feast day of St.Anthanasius. He was the Bishop of Alexandria in the 300 AD's. He was a theological advisor at the Council of Nicea and helped define the Trinity at a time when Arianism (an influential heresy denying the divinity of Christ) was dividing an empire. He clarified the confusion and helped others understand the Trinity as God the Father, God the Son, and God the Holy Spirit; all three eternal and divine.
St.Athanasius came to know the Truth himself, and that there was meaning and purpose to life. And he was willing to stand up for the truth in the midst of great opposition.
St.Athanasius' witness calls us to the truth of relational (Trinitarian life), and to stand up for that truth.
