Well, I was not referring to the common priesthood of all believers.  I was referring to the sacramental priesthood, which requires ordination.  Of course God transcends gender (see the Catechism of the Catholic Church, #239, 370, 2779).  But Christ has entrusted to the Church the mediation of all vocations; so, at least within the Roman Catholic Church, the Church can and actually do prevent women from being tested as to vocation for priestly ordination.  The Lord is, effectively, refused the right to call women and have their vocation tested.  Only the boys can apply.  So this is not really an injustice toward women; it is an injustice toward the Lord, by refusing to allow him to call women and have their vocations properly tested.
