As for me, I fail to grasp the part where you think that the act of kissing a book constitutes having an "other god." As for me, I believe that the 1st commandment requires us not to love anything or anyone as much as we love God. We owe God a special love and it should acknowlege His supreme position over all creation. Nothing that He has made should compete with our love for Him. Material goods and earthly pleasures are the most common of the "other gods" that vie for our attention.
As for the pope, I recognize that he follows the first commandment more strictly than my understanding of it. In the spirit of Mark, Chapter 10, this pope gave up everything to follow the Lord. I know that in his duties as priest, bishop, cardinal,and pope the last 50+ years he has adored, begged mercy, and given thanks to God Almighty everyday of his life, while bringing the gospel to perhaps 10's of thousands of hungry souls. It would be difficult to imagine anyone more committed to the 1st commandment.
As for your allegation that kissing a book, kissing a baby, kissing a championship trophy, or giving any sign of affection, show of respect, honor, or dignity to anyone or anything is automatic idolatry...well, that is silly.
