Protestant apologist James White has a few claims he regularly brings up against Catholicism, and which many Protestants blindly repeat. The two most common claims I've seen him make are asking Catholics "who is the Blessed Man of Romans 4:8?" and "Roman Catholicism cannot provide the true peace which the Gospel provides us". White says in his book and website (see here):
There can be no doubt what lies behind Paul’s use of the term peace in this [Romans 5:1] passage. The Hebrew steeped in Scripture knew full well the meaning of shalom. It does not refer merely to a cessation of hostilities. It is not a temporary cease-fire. The term shalom would not refer to a situation where two armed forces face each other across a border, ready for conflict, but not yet at war. Shalom refers to a fullness of peace, a wellness of relationship. Those systems [e.g. Roman Catholicism] that proclaim a man-centered scheme of justification cannot explain the richness of this word. They cannot provide peace because a relationship that finds its source and origin in the actions of imperfect sinners will always be imperfect itself. The phrase "we have peace" [Rom 5:1] in regard to God, properly means, God is at peace with us, his wrath towards us is removed.
This all sounds well and good, but all too often it turns out that things that sound good to human ears are often not actually what the Bible teaches (cf 2 Tim 4:3). White's lack of Biblical analysis in his presentation of how the Bible uses the term "peace" was suspicious to me, so I decided to see for myself how the Bible uses the Greek/Hebrew terms Peace/Shalom (here). Does the Bible speak of Peace/Shalom as something that is permanent and unconditional the way White makes it out to be? Here are some texts I've found that use the same Greek/Hebrew term "peace" as in Romans 5:1 that I think cast serious doubt on White's bold assertions:
