Actually all sacraments are equally significant. But you can consider 'Baptism' as the most significant because without receiving this sacrament you are not entitled to receive other sacraments.
The Church's greatest sacrament, the source and summit of her worship, is the Eucharist.

Baptism IS an important Sacrament for Catholics. It is the first Sacrament of 7 that we receive. Here is a link that will explain about the seven Sacramants of the Catholic Church. http://en.wikipedia.org/wiki/Sacraments_of_the_Catholic_Church It is the MOST important Sacrament for Catholics because without it we would not be able to receive the other six Sacraments.
It is the Catholic church that celebrates seven sacraments. Most Protestant churches recognise only two: baptism and holy communion. A few Christians do not recognise any sacraments at all, or say that there are an infinite number of sacraments (since a sacrament is just a symbol for some spiritual idea).
Holy Orders is the sacrament through which a man is ordained as a deacon, priest, or bishop by the laying on of hands and prayer. This sacrament conveys a special grace and power to serve the Church and administer the other sacraments. It is one of the seven sacraments recognized by the Roman Catholic Church.
Catholic & Orthodox follow the 7 Sacraments (though in Catholicism a person may only take at the most, 6 Sacraments). Protestants do not have all 7 Sacraments.

.Roman Catholic AnswerThe two Sacraments of Healing are Confession and Anointing of the Sick; the Sacrament of Ministry would be Holy Orders. I think you could make a case for all of the sacraments being "of ministry" especially baptism, confirmation, Eucharist, Marriage, and Holy Orders.
At the church I attend our sacrament is bread and water. The bread representing Jesus' body and the water representing his blood. I guess it sorta represents the atonement. I hope this advice helps you. Well I would first explain what a sacrament is and what is has to do apart of the liturgy or whatever your doing. I would then tell him the 7 sacraments in order of appearance and then tell him one by one what sacraments mean technicaly and symbolically to interpret the ritual. the seven sacraments are baptism, Eucharist, reconciliation, confirmation, marriage, holy orders, and anointing of the sick. they are special occasions, or important events in the life of a religious person.
The pope is a priest and bishop and. as such, can administer all 7 sacraments.
Roman Catholic AnswerThe seven sacraments of the Church are Baptism, Confirmation, and the Most Holy Eucharist known as the sacraments of initiation. Penance, Matrimony, Holy Orders, and Anointing of the Sick, or Unction.
