I don’t think there are many anti-Catholics that think they are being anti-Catholic. It seems like they are operating under the notion that they are bringing the “truth” to [misinformed] Catholics out of love (Jack Chick comes to mind too).
EG White’s writings are full of it. From chapter 3 of The Great Controversy:
“Satan once endeavored to form a compromise with Christ. He came to the Son of God in the wilderness of temptation, and, showing him all the kingdoms of the world and the glory of them, offered to give into his hands if he would but acknowledge the supremacy of the prince of darkness. Christ rebuked the presumptous tempter, and forced him to depart. But Satan meets with greater success in presenting the same temptations to man. To secure worldly gains and honors, the church was led to seek favor and support of the great men of earth, and having thus rejected Christ, she was induced to yield allegiance to the representative of Satan, – the bishop of Rome.”
“More than this, the pope has arrogated the very titles of Diety. He styles himself “Lord God the Pope,” assumes infallibility, and demands that all men pay him homage.”
It goes on to say how the pope usurped the power over Christ’s church (forgetting that Jesus gave Peter the authority), Satan, through the Pope concealed and suppressed the Scriptures (forgetting that it was Catholic monks and monastics who painstakingly copied and protected the scriptures during the various barbarian invasions).
*It was Rome, through pagan Constantine that decreed that Sunday be called the Lord’s Day, thus taking worship away from Saturday. *
Justin Martyr in Chapter LXVII (67) of his First Apology writes: “And on the day called Sunday, all who live in cities or in the country gather to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits: then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things… But Sunday is the day on which we all hold our common assembly, because it is the first day on which God, having wrought a change in the darkness and matter, amde the world; and Jesus Christ our Savior on the same day rose from the dead. For He was crucified on the day before that of Saturn (Saturday); and on the day after that of Saturn, which is the day of the Sun, having appeared to His apostles and disciples, He taught them these things…”
Although the Great Controversy was written in the 1840s (?), it still contains inflammatory words such as Papist, Romish, Romanist. The book is still being made widely available and freely mailed to anyone.
