Protestants reject the idea of Purgatory but usually believe in eternal hell. God freely chooses to forgive the sins of some, and they can enter heaven, but forgiveness is only possible through God's grace. Free will means people have some responsibility for effecting their own salvation, through a person’s own works - both in actively choosing God through faith, and in a life of growing conformity to the teaching of Christ. Protestants believe Catholics venerate Virgin Mary excessively. This borders on idolatrous worship with Mary appearing to have primacy over Jesus at some times. There are few biblical references to support the Catholic Marian dogmas — which include the Immaculate Conception, her perpetual virginity and her Assumption into heaven. This is why they are rejected by Protestants.
