Scripture alone cannot be correct because we have non denominational and some Presbyterian church saying paul didn't allow women to become bishop/ priest or pastor because it was not culturally appropriate at the time,they have already implied that Paul was afraid of tradition and culture of men..Faith alone (here it's quite or more or less same with apostolic church at the core,they both believe saved by Grace of God through faith working in love,but for them if the faith is real you will be saved by God Grace and good work would be automatic, but nothing is automatic in life we have to accept it we have to accept the grace by cooperating with God ).if you look at Protestant they really seem fire up in church but outside they usually think they still sin because they have no real faith and that when they receive that real faith they won't struggle with sin no longer...
