Whatever the case, there is no wisdom in Christians (especially the supposed earthly head of the Christian church) bowing their heads and kissing the sacred texts of different religions. There is literally no excuse for such conduct, as such communicates endorsement. Christ made an exclusive truth claim (John 14:6). If other belief systems are acceptable to God, then Christ would be a liar and false messiah. That charge would be blasphemous to the utmost.
If the pope is truly the Vicar of Christ on earth, then why would he display so much reverence for a religion that fundamentally contradicts his own? His action so clearly resembles that of an apostate (Galatians 1:8-9; 2 John 9-11). He also could have mislead those who are unlearned by his irresponsible act. Why then do Roman Catholics try so hard to defend this sort of behavior? The rightful thing to do would be to simply admit that the pope erred. Moreover, it is not as though we will ever see an imam kissing the Holy Bible.
It seems that the pope these days will do anything to gain political influence. That appears to be the motivating factor behind the Vatican associating with Islam. The Roman Bishop definitely seems to be a figure who has charisma. Even today, millions flock to Rome just to behold him as he lectures. Faithful Roman Catholics bow before him and kiss the hand which wields the ring molded for his coronation. All of this is idolatry, pure idolatry.
