1 Timothy 3:12

Let deacons be husbands of one wife, ruling their children and their own houses well.

Let deacons be husbands of one wife ... This disqualifies any woman from serving as an official deacon. The notion that Paul laid down hard and fast regulations regarding the marital status of both elders and (male) deacons, and he then authorized a whole new echelon of (female) deacons without specifying any marital qualifications whatever, is too unreasonable to believe. No! The people who are determined to appoint female deacons will have to find their authority and their guidelines somewhere else than in the New Testament. See comment on this clause under 1 Timothy 1:2.
