"Purgatory-Not Biblical - Matt. 12:32 “And anyone who says a word against the Son of man will be forgiven; but no one who speaks against the Holy Spirit will be forgiven either in this world or in the next.” Jesus thus clearly provides that there is forgiveness after death. Forgiveness is not necessary in Heaven, and there is no forgiveness in Hell. This proves that there is another state after death, and the Church for 2,000 years has called this state purgatory.
** Veneration of Mary**-Not Biblical - All generations shall call her blessed.
** prayer to saints and angels**-Not Biblical - All believers, living, dead, and spiritual (angels) are united in the Communion of Saints. Since Paul exhorts us to pray for one another, this includes those in Heaven and Purgatory, we must ask them (pray) for their prayers on our behalf. This is no different than Me asking you to pray for me. Scripture says that they can see us, they are a “cloud of witnesses”, there is more joy in Heaven over one who reforms, and Revelation shows the saints presenting our prayers before the Throne of God.
grace and works for salvation-Not Biblical - Parable of the Sheep and Goats shows Jesus sending the Goats into Hell because they did not feed Him, clothe Him, care for Him. They called Him “Lord” but they did not care for those in need. "Not everyone who says to me Lord, Lord, will enter the Kingdom of Heaven, but only those who do the will of my Father in Heaven."
papal primacy-Not Biblical - Peter is given the Keys to the Kingdom, and is the Rock on which He will build His Church.
** papal infallibility**-Not Biblical - The Holy Spirit will guide them unto all truth. Jesus said this, He wouldn’t lie.
transubstantiation-Not Biblical - John 6, all the last supper discourses show this is wrong.
Sacraments-not Biblical - Since Baptism is, as shown next, this is obviously not true. Also 10 commandments say adultuery is a sin, since marriage is required to commit adultery it is sacramental - fornication is for the unmarried, adultery for the married.
** Baptism for salvation**-Not Biblical - Acts 2:38 Peter (said) to them, "Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the holy Spirit.
** Complete devotion to church law**-Not Biblical - Scripture says the Church is the pillar and foundation of all truth.
** Repetitive Confession Prayers**-Not Biblical - Don’t know what a confession prayer is really, but - Rev 4:8 The four living creatures, each of them with six wings, were covered with eyes inside and out. Day and night they do not stop exclaiming: “Holy, holy, holy is the Lord God almighty, who was, and who is, and who is to come.”
Indulgences-Not Biblical - The Church dispenses the graces of God. This power has been abused in the past, but that doesn’t invalidate it.
** Forced Celibacy**-Not Biblical - also not a doctrine feel free to disagree with it. This is a discipline not dogma. It is also just a discipline for the Latin Church, eastern rites have married priests. Paul says those who can be celibate should for the sake of the Kingdom. Also Jesus was celibate.
** All salvation from Roman Church**- Not Biblical - this is ridiculous.
** Apostolic Succession**-Not Biblical - We see Paul instructing Timothy on how to handle his work as the new bishop, he exorts timothy to do likewise and not lay hands on any one too quickly.
** Power to Anathemize**-Not Biblical - Matt 15:17 - If he refuses to listen even to the church, then treat him as you would a Gentile or a tax collector.
Hope this helps.
