Why are the so-called "women can't pastor" scriptures written to the churches in Corinth, Ephesus, & to Timothy?
Corinth was known for its worship of Aphrodite, while Ephesus was famous for the cult of Artemis (also known as Diana). Both goddesses had temples dedicated to them and were revered by the local populations. Since these temples dominated the cities, the roles of men & women were reversed. So when these people were saved, they brought their idolatrous habits into the church with them. Thus Paul's teachings specifically to them.
What about Timothy, then? Timothy was chosen by Paul to be over all the house-churches of Ephesus, so he had to be instructed on how to specifically minister to them.
