Ministry to do Mass/Divine Liturgy appears to equate to office, right? The priestly office occupied by an ordained laity believer.
Perhaps this helps to explain the Melchizedek and "Aaronic-like" difference:
Catholic Encyclopedia:
"The simple fact that numerous heretics,...
I dont know how readable can be for a Protestant the Catholic Encyclopedia, that is a 100 years old text that requires some knowledge of specific vocabulary/doctrine. Here this text points out the difference between the Consecration of the Eucharist, that is the "made present" of the sacrifice of the Cross, and thus offered by Christ to the Father (the sacrifice), and the eating/drinking of the Holy Body and Blood that is offered by Christ to any Christian (the sacrament) who receives the sacrament for his own sanctification.
Perhaps to point out the difference between the priesthood of Melkisedek and the hierarchical priesthood it is better to refer to the Catechism of the RCC (link):
1546 Christ, high priest and unique mediator, has made of the Church "a kingdom, priests for his God and Father." The whole community of believers is, as such, priestly. the faithful exercise their baptismal priesthood through their participation, each according to his own vocation, in Christ's mission as priest, prophet, and king. Through the sacraments of Baptism and Confirmation the faithful are "consecrated to be . . . a holy priesthood."
1547 The ministerial or hierarchical priesthood of bishops and priests, and the common priesthood of all the faithful participate, "each in its own proper way, in the one priesthood of Christ." While being "ordered one to another," they differ essentially. In what sense? While the common priesthood of the faithful is exercised by the unfolding of baptismal grace - a life of faith, hope, and charity, a life according to the Spirit - ,the ministerial priesthood is at the service of the common priesthood. It is directed at the unfolding of the baptismal grace of all Christians. the ministerial priesthood is a means by which Christ unceasingly builds up and leads his Church. For this reason it is transmitted by its own sacrament, the sacrament of Holy Orders.
About the Aaronic priesthood:
1540 Instituted to proclaim the Word of God and to restore communion with God by sacrifices and prayer this priesthood [Aaronic] nevertheless remains powerless to bring about salvation, needing to repeat its sacrifices ceaselessly and being unable to achieve a definitive sanctification, which only the sacrifice of Christ would accomplish.
1541 The liturgy of the Church, however, sees in the priesthood of Aaron and the service of the Levites, as in the institution of the seventy elders, a prefiguring of the ordained ministry of the New Covenant
