They are as different from each other as the world is from the church.
I feel that those who advocate a hybrid of 'Position-Servant Authority' advocate a mixing of the world with the church.
Here are the differences between 'Position-Expediency' (P-EA) and 'Servant-Example' Authority (S-EA) as I see them:
Position-Expedient Authority (what we have today in churches of Christ) divides the body of Christ based on unequal status. Servant-Example Authority (what I believe is found in 1 Peter 5:1-7 and the rest of the NT) unifies the body of Christ based on equal status, but acknowledges spiritual gifts of young and old alike.
P-EA creates a separate class of Christians. S-EA includes all Christians. There is no need to ask the question "why give qualifications for elders and deacons?" in disbelief when the purpose for their qualities is to set the example for all to follow in serving others when needs arise. If one must have a type of "directive" authority to meet the needs of others (Acts 6), then others may be persuaded to help that leader (elder/deacon) based on his character--not because they are fearful or have been shamed into 'obeying' them. If that elder or deacon cannot persuade others to help him meet the need, then maybe he needs to change his behavior, or perhaps the problem is with the followers.
P-EA allows for misbehavior to often remain unchecked/unchallenged and unchanged. S-EA demands that behavior remain blameless, because one must be a doer of the work--not a 'constant delegating authority' of others who do the work. Wisdom and advice from those no longer able to do what they formally could may persuade the younger.
P-EA allows for men to make laws in addition to the NT to rule others. S-EA demands all Christians keep Jesus' laws. Self control is what is commanded Christians, not 'other-control.'
