When you say the Church has never codified that only men men be ordained to the priesthood, it has.
In the early centuries of the Church various heretical churches did ordain women. Numerous Councils, Synods and bishops outlawed this practice as an abuse and also suppressed the practice of deaconesses carrying out liturgical functions (e.g. abbesses reading the Gospel, etc).
The Church is on pretty firm ground, a rock in fact, in declining to ordain women.
