Then why do Catholics need them?
They need them like they need Mary. "Does the Catholic Church worship Mary?" If you ask any Roman Catholic, they will flat out reject that the church worships Mary or idols. What they will say is that they "venerate" Mary and relics. Well, let's look at the definition of "venerate”. The English word "venerate" comes from the Latin word "veneratus", which means: "worshipped, adored, revered, venerated." So the word "venerate" also means to worship.
Any Gospel that preaches "Jesus and" is a false, misleading and counterfeit Gospel. When I was raised as a Roman Catholic we were taught that the Protestant fold fell away from the truth. I now can see lock, stock and barrel it was Rome that fell away from the truth and it was truly the Reformers who restored the church to the truth of the Gospel, “PROTESTED” all the nonsense Rome added and restored the church to the way it was intended to be by adhering to the Gospel message of salvation through faith alone in Christ alone and his redemptive act on Calvary for all who place faith in Him alone for salvation and not Rome’s heretical additions.
Today I totally reject all RC Marian teachings, including the Immaculate Conception, that Mary was immaculately conceived in the womb of her mother Anne and the Assumption, that Mary was assumed into heaven to be at the side of her Son Jesus and the Father and the Holy Spirit; some say almost like a 4th person of the Trinity, which is an obvious contradiction or Oxymoron statement! Both teachings are not supported in scripture and both teachings were proclaimed under the RC doctrine of papal Infallibility on matters of faith and morals which I also reject and is another reason I am now a Protestant and No longer a Roman catholic. .
I am a Reformed Protestant now, a Presbyterian and I do not condone the veneration of Mary, because I believe as a Protestant all glory and honor is to God alone. I do not believe in the Rosary or any Marian devotions because there is no biblical basis for it.
Below is a picture of Roman Catholics worshiping the false mary of Roman Catholicism who is not the Mary of the bible, the mother of the earthly Jesus, the Messiah. She is however not free of sin as Rome teaches.
I do not accept the RC teaching of the Immaculate Conception or the Assumption of Mary into Heaven because it is by papal decree under the doctrine of Vatican I and II on papal infallibility which says the pope speaking ex Cathedra from the chair of Peter on matters of faith and morals only can proclaim what Catholics are to believe as truth even if not in scripture. I also do not any longer accept and believe in the authority of the Bishop of Rome, and I renounce my former Roman catholic faith completely!
I now follow the Reformed Confessions which outline what we believe as Reformed Protestants, I subscribe chiefly to the Original Westminster
