Of course he is, and Catholics read and study the Bible just like Protestants do. The question is according to whose assumptions and opinions should one read and interpret the Bible? Should we seek to understand Scripture according to the authoritative teachings of Christ's one historic Catholic Church, or according to the opinions of one of the myriad recently-invented, man-made non-Catholic sects in existence today, with more being invented every week?
The simple fact is that when one reads the Bible, he interprets it according to someone's doctrinal tradition, whether it's Catholic Tradition, or one of countless non-Catholic traditions.
Catholics seek to understand Scripture in light of the ancient teaching Tradition of Christ's Church, while non-Catholics endeavor to understand it in light of the teachings they've derived from their chosen man-made non-Catholic sect(s). Either way, however, everyone interprets the Bible according to his chosen doctrinal tradition.
Peter in no way negates or denies this basic fact. Indeed, the New Testament itself affirms that Scripture must be understood according to the authoritative teachings of Christ's one historic Church (the apostles/bishops in leadership), and not according to the mere opinions of non-apostolic/non-episcopal lay believers (e.g., Mt. 28:18-20; Lk. 10:16; Ac. 16:4; 2 Thess. 3:4; 1 tim. 3:15; 1 Jn. 4:6).
So much for your article's erroneous assumptions and assertions on this point.
