Evidence of women in ministry is found in Acts and Romans. 

So desperate was the 3rd Century Church to reestablish “cultural norms” to help ‘reform’ the policies of the early church, scribes actually began messing with the New Testament manuscripts.  Just small things, but very weighty. 
In the most ancient manuscripts that we now have, in Acts 18:26, Priscilla seems to be the primary teacher of Apollos.   Centuries later, a copyist switched the order of names, placing the name of Priscilla's husband, Aquila, first. 
In Romans 16: 7, someone name Junia—a woman's name—is said to be "significant among the apostles," but a later scribe turned 'Junia" into "Junias," a man's name.
