Whether the Pope is christian or not, I will not judge.
But I am sure he follows catholicism, which is a religion, which actual draws people away from a personal relationship with God.
Christianity is a relationship with God, Jesus Christ and the Holy Spirit.
It uses religion i.e. rules or standards to help maintain that relationship with Him, the vertical and with your fellow neighbor, the horizontal.
When you refer to it as a religion you are only refering to its aspects, not Christianity itself.
Christianity is trusting in Jesus before it is anything else.
God bless you and I pray that you come into a relationship with Him.
