The pope, the successor of Peter, does, in fact, call himself, the servant of the servants of Christ, and the reason he does so is for love of Christ, So he does, like Peter, consider himself the servant of Christ.
Also, 'evangelical', of course, comes from the Greek word 'evangelion' for Good News. The pope IS evangelical because he proclaims the Good News of the Gospel that Jesus came to bring salvation. It is also good news that he said he would be with his Church until the end of time to lead her into the fulness of truth. That truth, though, from the very beginning of the Church, was difficult to comprehend without someone to teach officially on behalf of the Church. Thankfully, Jesus gave her leaders to guide her into truth.
