Now that he is officially installed as the 266th pope of the Roman Catholic church, Pope Francis has no other way to go but sit down and assess just how he will go about doing his priestly vocation to shepherd people into the faith as well as maintain integrity in leading a crisis-reeked religious institution.

Only exactly a week old into office, Pope Francis has shown how far detached he is from the customs and ways set before his predecessor - from his choice of papal vestments, symbols, language, even personal demeanor.

Such behaviour has already endeared him to the 1.2 billion-strong followers of the Catholic faith, and perhaps even some of the cynics.

Still a question remains - just how long can the new pope be able to sustain such behaviour which others had described as a wave of fresh air compared to the rigid, complexed hierarchy of the previous one?

"He will be changed by the office," Cardinal Francis George, Archbishop of Chicago, told Chicago Tribune. Although Cardinal George strongly believed Pope Francis will fight tooth and nail not to be swayed by the complexities of his job, his personal dedication and the manner he delivers them might be affected somehow.

"The challenge now for him is to translate a personal virtue into an institutional characteristic, and I'm not sure how you do that," the 76-year-old American cardinal of the Catholic Church said.

Cardinal George cited Pope Francis' homily in which he urged everyone to protect all of creation and embrace the poor, advocacies which are actually close to the heart of the reigning supreme pontiff.

Citing his own experience, Cardinal George relayed the realities of his job as Archbishop of Chicago somehow affected his personal virtues. Initially he told himself to regularly visit the clients being served by Catholic charities.

But half a year later into the post, he admitted it was already hard to fulfill that personal obligation as his administrative duties got bigger and wider. He ultimately had to pass on the work that he no longer was able to accomplish.

With that reality, Cardinal George believed Pope Francis would be forced to alter his personal obligations in trying to maintain a balancing act in running the Roman Catholic hierarchy.

"He's a man of great integrity. He won't do anything that doesn't seem right to him," Cardinal George said.
