My understanding of the term 'super-apostle' comes from Paul's references to various 'competitors' of his in the 1st century church in 2 Corinthians 11 - it is rendered such in some modern translations. Basically, Paul is being sarcastic, based on the self-promoting attitudes of some preachers - elsewhere he talks about sectarianism in the church, with some boasting that they follow Paul, some Apollos and so forth - 'my apostle is better than your apostle'!. But Paul insists that there is no cause for rivalry and boasting; all true apostles do the work of Christ who commissions and anoints them, and to whom they are to lead folk; they are their to build His Church, not promote their own careers and following. Anything else is little less than a 'personality cult' - a very dangerous and divisive force.
In modern day terms, the title 'super-apostle' could be applied in a similar way to the self-promoting leaders of various movements and streams within charismatic Christianity, who seem to vie with one another for 'position' in the Kingdom - each claiming to be 'better' or 'more anointed' than the next, 'proving' their apostleship by the abundance of their revelations, the magnitude of their miracles, or the number of their converts (or even, in some cases, the size of their bank balance!). In actual fact, according to Christ's teaching such behaviour totally refutes their claim - for the first is to be last, and he who would be 'greatest' should be servant of all.
We do well to remember that the role of the apostle, like any other ministry gift, is first and foremost a position of service to the Body of Christ, and not the source of power, influence and 'charisma' (in the Hollywood sense). The ministry is not to be viewed as a means of gain - financial, social or psychological - and those who stray down that path stand to lose everything.
