God revealed Himself as the Father, the Son, and the Holy Spirit. What that signifies as far as the Father is concerned is largely mysterious, but it not irrelevant, and it is not dispensable.

For purposes of this discussion the Holy Spirit is not directly relevant.

The sacerdotal priesthood, however, is iconic of God the Son. God the Son was in fact a male.  In instituting the sacrament of orders He ordained only males, and this practice is part of the Church’s divine constitution, just as the existence of seven sacraments, the requirement that the Eucharist be only wheaten bread and grape wine, and the other doctrine of the Church.

To the best of my knowledge no one has taught that women are not created in God's image or likeness.
