The cathedral, which began the first of four services today at 9am on Sunday, opened a book of condolence for the eight people killed when three men drove a van into pedestrians before getting out of their vehicle and launching a knife attack in Borough Market.
The Very Reverend Andrew Nunn, Dean of the cathedral, told the BBC ahead of the first service that despite what had happened: "You know there are so many, many, many millions and millions of good people around the world."
He continued: "Life can be affected by a few evil people as we saw last week.
"Actually the strength of goodness is so much greater and that's what we are going to be proclaiming today as people come into church, and we'll be continuing to do that as we rebuild this community together."

The re-opening comes after the cathedral closed as it was in the area that was cordoned off in the days after the attack on Saturday 3rd June. Police tape was lifted a week after later.
During one of the morning services the Bishop of Southwark praised the "rapid" response of the emergency services.
In a statement the Cathedral said: "We are grateful to the police and other emergency services for all that they have done, at great cost to themselves, in recent days.
"We are grateful also for all the messages of support and encouragement we have received from around the world. We continue to pray for all those affected by Saturday's events."
