The Trinity is always described as God the Father, God the Son, and God the Holy Spirit.  The Father is the first person in the Trinity.  God was commonly referred to as the Father in Judaism as was passed on into Christianity.  It’s commonly used as a metaphor in a sense where he watches over us like a father would watch over his children.  He is the life-giver.  God the Father also refers to God being the father of Jesus Christ.  This is reaffirmed in the Apostle’s Creed, and is a core belief in a large majority of Christian denominations.

How is God Our Father

He gave us life.  He fathered creation.  He watches over us everyday.  He protects us from harm.  He’s also been given this title because of his participation in human affairs.  God is an all knowing, all powerful being that doesn’t observe, but is a force who is present in our daily lives.  He is the perfect father.  Anything that He allows to happen is there to help us learn to make us stronger.  This is to benefit our time on earth.  We need to be strong with all the terrible things that exist in our world.  Whether you live in one part of the earth or the other, there are challenges.

Even though a father is masculine, God is usually regarded as not having a biological gender.  The Catholic Church’s view is “God is neither man nor woman: he is God.”  The masculine term used may have something to do with the patriarchal structure of religions and many societies.  One could even say the term “mother” would fit considering God is a life-giver and “gave birth” to creation.  I’m sure there are some who would radically disagree with that statement though.

One God and Father of all, who is above all, and through all, and in you all.

Ephesians 4:6

But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.

1 Corinthians 8:6

And call no man your father upon the earth: for one is your Father, which is in heaven.

Matthew 23:9
