All believers are called to be servants or ministers of the Lord. This is the general meaning of the Greek word 'diakonos,' which is occasionally translated 'deacon' in the Bible. From this standpoint, yes, a single woman can be a deacon (a servant, a minister). This word is also used, however, to refer those who are appointed to a special responsiblity of serving the assembly. These are the people we commonly call deacons. From this standpoint, the Bible does not indicate that women were ever appointed to this responsibility. The word translated 'deacon' is only found in the masculine gender when speaking of these people (see Philippians 1:1 and 1 Timothy 2:8-13).
