Protestant religions teach that salvation depends on faith only.
Salvation (Losing Salvation) - Catholics believe that salvation is lost when a responsible person commits a mortal sin.
Similarly, Protestants believe hell is a real physical place of punishment which lasts for all eternity but rejects the concepts of limbo and purgatory.
Immaculate Conception of Mary - Roman Catholics are required to believe that when Mary herself was conceived, she was without original sin. Infallibility of the Pope - This is a required belief of the Catholic Church in matters of religious doctrine. The Lord's Supper (Eucharist/Communion) - Catholics believe this sacrifice is Christ's body and blood physically present and consumed by believers ("transubstantiation").
Some denominations teach that a person can lose their salvation.
Statues - Catholics give honor to statues and images as symbolic of the individual saints.
Many Protestants consider veneration of statues to be idolatry.
Visibility of the Church - The Catholic Church recognizes the hierarchy of the church, including the laity as the "Spotless Bride of Christ." Protestants recognize the invisible fellowship of all saved individuals. It can be regained through repentance and the sacrament of confession.Protestants usually believe, once a person is saved, they cannot lose their salvation.Protestants believe forgiveness of sin is received through repentance and confession to God directly without any human intercessor.Hell - The New Advent Catholic Encyclopedia defines hell in the strict sense, as "the place of punishment for the damned" including limbo of infants, limbo of the Fathers, and purgatory.Purgatory - Catholics believe purgatory is a state of being after death in which souls are cleansed by purifying punishments before they can enter heaven. Right to Life - The Roman Catholic Church teaches that ending the life of a pre-embryo, embryo or fetus cannot be allowed, except in very rare cases where a life-saving operation on the woman results in the unintended death of the embryo or fetus.
