The anointing of the sick is administered to bring spiritual and even physical strength during an illness, especially near the time of death. It is most likely one of the last sacraments one will receive. A sacrament is an outward sign established by Jesus Christ to confer inward grace. In more basic terms, it is a rite that is performed to convey God’s grace to the recipient, through the power of the Holy Spirit.
When Jesus came, he elevated matrimony to the same status it had originally possessed between Adam and Eve—the status of a sacrament. Thus, any valid marriage between two baptized people is a sacramental marriage and, once consummated, cannot be dissolved. Jesus, therefore, taught that if anyone so married divorces and remarries, that person is living in perpetual adultery, a state of mortal sin.
All pardon for sins ultimately comes from Christ’s finished work on Calvary, but how is this pardon received by individuals? Did Christ leave us any means within the Church to take away sin? The Bible says he gave us two means.
Are all of our sins—past, present, and future—forgiven once and for all when we become Christians? Not according to the Bible or the early Church Fathers. Scripture nowhere states that our future sins are forgiven; instead, it teaches us to pray, "And forgive us our debts, as we also have forgiven our debtors" (Matt. 6:12).
For a sacrament to be valid, three things have to be present: the correct form, the correct matter, and the correct intention. With baptism, the correct intention is to do what the Church does, the correct matter is water, and the correct form is the baptizing "in the name of the Father and of the Son and of the Holy Spirit" (Matt. 28:19).
"Between heresy and schism there is this difference, that heresy perverts dogma, while schism, by rebellion against the bishop, separates from the Church. Nevertheless there is no schism which does not trump up a heresy to justify its departure from the Church."
~ St. Jerome, (In Ep. ad Tit., iii, 10), remarking on how practically and historically, heresy and schism nearly always go hand in hand.
