Very good. He’s respectful, no staw arguments, he looks at the data or councils, confessions, catechisms, and core beliefs of Roman Catholicism and compares them to Protestant dogmas. It is a scholarly work, not a “bash Rome” book. For example He says, “If you ask a Protestant the difference between Protestantism and Roman Catholicism, the Protestant will typically say: “We believe that justification is by faith but Roman Catholics say it is by works. We believe it is by grace but Roman Catholics say it is by merit. We believe it is through Christ but Roman Catholics believe it is through one’s own righteousness.” These are terrible slanders against Rome. From the sixteenth century to today, the Roman Catholic Church has said that justification requires faith, the grace of God, and the work of Jesus Christ. The debate arose because Protestants said justification is by faith alone, whereas Rome said justification requires faith plus works, grace plus merit, Christ plus inherent righteousness. It was those pluses that became so problematic in the sixteenth century, particularly with respect to the works of satisfaction that were part of the sacrament of penance.” (Are We Together?, Chapter 2, Justification, pg 34). Sproul examines the differences as stated by both sides, even letting the reader read The Council of Trent, Vatican I and II.
