I assume that you know the word “Protestant” comes from the word “protest.” What do you think they are protesting? They are protesting the Magesterium of Catholic Church, they are protesting the traditional teaching of the church, they are protesting the validity and infallibility of the Pope, they are protesting the Eucharist, they are protesting Mary as Queen of Heaven and Earth, they are protesting the authority of priests to forgive sins, and on and on and on. Protestants today are not themselves heretical because they have not personally rejected the Catholic church and her teachings. But their beliefes most assuredly are heretical. Yes, Protestant baptism is valid because they do it according to the teachings of Jesus Christ. But that does not give validity to all of their many heretical teachings. Anglicans most definitely do NOT believe the Eucharist is a sacrament, at least not in the sense that the Catholic Church does. They administer it as if they do, but they do not believe in transubstantiation. Only the Catholic church believes this.
