The Pope did say in order that all doubt may be removed ..."Wherefore, in order that all doubt may be removed regarding a matter of great importance, ......,"
This is a direct quote cut and pasted from OS.
There is no need for the Church to define any belief until that belief is comes under attack. The issue of ordaining women has only come to the fore over the last fifty years or so. Prior to that it was universally accepted that only men could receive the Sacrament of Holy Orders. Whenever there were abuses popes and councils suppressed them.
Since the agitation for women priests began due to Protestant practice,  the Popes Paul VI and John Paul II and the CDF have made it quite clear that the ordination of only men is part of the deposit of Faith; they are supported in this by the Orthodox Churches.
You obviously disagree with 2000 years of Tradition, upheld by popes and councils up to the present day; that is your privilege. I accept the teaching of the Church as laid down in OS.
