Father Aiden Troy, from St. Joseph's Roman Catholic Church in Paris, told Premier that people are trying to stay strong: "After the Januray Charlie Hebdo there was a defiance - and that was a very genuine defiance - over a million people on the Sunday standing on the streets saying 'I am Charlie, I am Paris, I am whatever, noone's going to put me in - there is an element of saying we almost have to try and be defiant, we have to try and be normal."
130 people were killed when six coordinated terror attacks took place across Paris on November 13th.
Father Aiden Troy said it makes people in Paris think about those living in conflict zones under the constant threat of terror: "I think of all the different places that have had this for months and years, but honestly I think we in Paris, we in France, now realise perhaps the enormity of what's going on in our world - and perhaps this could be a uniting factor."
"The danger is that this could become the way we're going to have to live - and that's what people are trying to balance - I know I'm trying to do it.
"I was on the Metro twice last night, it was packed - workers coming home, people going out and that, and of course you say to yourself 'is this mad?' What's the alternative - you don't go out?"
French president Francois Hollande has promised the families of those killed and wounded in the Paris attacks that he will do everything to destroy the "army of fanatics" responsible.
Mr Hollande spoke in front of his government, families of the victims and soldiers at a memorial service inside the courtyard of Les Invalides.
The names of the 130 dead and their ages were read aloud in the ceremony.
The French national anthem played by a military band closed the ceremony honouring the dead, and Mr Hollande left Les Invalides walking alone.
He announced on Thursday that Russia and France will coordinate their military strikes against Islamic State, which claimed responsibility for the attacks.
