First of all, the elders, the pastors are addressed, given exhortation, and then the people generally. The apostle Peter was also an elder, as he tells us.
We too have seen something of the glory of Christ if we are truly born-again. We have seen just something of the glory of Christ. It's all part of what we call the earnest of the inheritance, the down payment or foretaste of glory that we receive. We have tasted the pity and compassion, which is in the love of Christ. You look back at some of the things that have happened to you, and some of your unworthy reactions, and some of your slidings, and the things you've done, and you think of the patience of Christ: that he still blesses me and helps me.
Calvin comments that if Peter had the gift of primacy, now was the time to assert it, for he might have used any such authority given him by the Lord to exhort the other leaders of the church not to ignore it, but instead he ignores even his apostleship in order to come alongside them.
There are those who teach (and this is quite commonly believed by more liberally minded people with a very low view of the precision and the inspiration of Scripture) that in the New Testament there were all kinds of different officers in the church and the text is really somewhat confused, one minute calling them by one name; one minute calling them by another. That is very sloppy reading and poor understanding of the word of God. There is a pattern church in the word of God. There is great precision here and these verses before us are rather interesting in that they take a number of equivalent terms for eldership and they put them all together. If only the people who criticise would notice these things. It isn’t one term here, another term somewhere else. There are different terms, but uniquely they are brought together in these verses of chapter 5 of 1 Peter. Why are there different terms? The terms speak for themselves. An ‘elder’ suggests something of the stature of the person – not a novice, not a youngster, somebody (hopefully) more experienced, more mature in the things of God – whereas some of the other terms like shepherd or pastor speak of function, shepherding, oversight. Each term speaks of one of the functions. The stature, then the functions of the office bearer. But there is another term in our King James Version translated ‘bishop.’ Elder/bishop, the two terms are interchangeable in the New Testament, but where does this term bishop come from? It is a rather clumsy translation of the word for overseer, or overwatcher, so you have got an elder one minute, then a shepherd, then an overwatcher, the bishop word. Is that word here too? Yes: ‘Feed [Shepherd] the flock of God which is among you, taking the oversight’ – that is the bishop word, the oversight, an overseer, overwatcher. So you have got several terms there beautifully combined together. There is no confusion. The elder is also an overseer (bishop, in our King James Version) and also a shepherd, which is another term for pastor. They are all here.
