God, in relation to creation, is male.

God and the early Christians all call God male. God is male in relation to us, as his church. And God is male in relation to us as his creation. 

God is neither male nor female in the sense we are, except Jesus in his physical form. The Greek Orthodox tend to give our spirits a female gender whether male or female, but I do not believe we as Catholics do. 

To a Catholic the soul of each human is either male or female as the soul is not separate from the body but is someone's whole person and the Church teaches our souls and bodies are either male or female at their cores. 

The sense in which God is male is not in the sense of human gender, where God does not have a gender, but in a far deeper sense. Baptise someone in the name of the Parent, Child and Holy Spirit instead of the Father, Son and Holy Spirit, and the Catholic church will not deem them as validly baptised. This is because the gender of God in fact reveals something important in its use in the bible and as an essential reference to the nature of God. God is spirit, and does not have human gender, but does have a deeper sort of gender which is essential to his very nature and to monotheism being the form of Christian religion as opposed to pantheism.

God is always referred to as what one might term a he, a masculine figure, in the bible, indicative that he is overall a he in relation to us. To borrow from the same sort of left wing movement which wants God or the Holy Spirit to be female, it would be rather unbefitting to call God female when he self identifies as male. 

'Jesus Promises the Holy Spirit

15“If you love me, keep my commands. 16And I will ask the Father, and he will give you another advocate to help you and be with you forever— 17the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be c in you. 18I will not leave you as orphans; I will come to you. 19Before long, the world will not see me anymore, but you will see me. Because I live, you also will live. 20On that day you will realize that I am in my Father, and you are in me, and I am in you. 21Whoever has my commands and keeps them is the one who loves me. The one who loves me will be loved by my Father, and I too will love them and show myself to them.”' John 14 NIV.

(παράκλητος, advocate/comforter, is an accusative masculine singular noun. Male intercessor summoned to help or comfort. The pronouns in proper translation thus inherit from that noun as masculine. I will give an example from French. Whether il is to be translated as it or he in that gendered language which I am most familiar, depends on the noun. It inherits masculinity or neutrality. Il est blanc, where il is Jacques can only be translated as he is white, but where il is bread (pain), can only be translated as it is white. Translating it as: Jacques? It is white or bread? he is white, is to translate in a manner which is not conistent with a knowlede of French and gendered languages in general. Bible translators have been inserting he as the pronoun for hundreds of years for the simple reason that the Greek indicates it is appropriate. The masculinity is inherited into the pronoun from the main noun of Advocate, just as il can only be he where il is my friend Jacques.)

Jesus obviously was a man, and Jesus calls God the Father Dad essentially, in parts of scripture, and tells us to call God the Father Our Father. Scripture has Jesus referring to both the Father and Spirit as male, and to himself as the Son of Man, a male.

Overall, it goes back to the root meaning of words. That which is female is that which contains, such as the universe or the Church, or a ship for that matter. That which is male is that which seeds life into that which contains, such as The Holy Trinity. God is male and we as church are female in relation to God, but our souls are either male or female depending on our bodies and our DNA and receptivity to testosterone and oestrogen in the womb.

Were God or any part of God female, we would be pantheists, like the pagans, not monotheists. As it is, God is Being in the true sense of being, He is that which gives being and life to all other things that can be or have life. God, in relation to creation, is male. He can have female associated traits, and does, but in his core relation with us He is male in the most meaningful core sense, that of he who sows the seeds of life.
