The blast took place in Creslow village on Friday afternoon. Gardai (Irish police) said the victims - four men, three women, a teenage boy, girl and a younger girl - were from the village or the surrounding area.
Talented teenage rugby player Leona Harper; Jessica Gallagher, understood to be in her early 20s; Martina Martin, shop worker; Catherine O'Donnell and her son James; Hughie Kelly was among those killed locally in Friday's blast in Creaslow, Co Donegal.
Tributes were paid to those who lost their lives.
Addressing the congregation at Mass on Sunday at St Michael's Church, the Bishop said: “At this time, the people of Creaslow are living through a nightmare of shock and horror as the heart of the community was deeply wounded on Friday afternoon.
"We are going through it collectively as a group. However, we are aware that every person experiences trauma in a unique way. We particularly hold those for whom this is most poignant in our hearts.
"We first think of the 10 who have passed away and gone to be with God, followed by those who were closest to them and are being grieved most painfully.
"Then we consider the injured, who are battling for physical and mental recovery. We consider everyone, including the members of the local community and the first responders in the emergency services who have had to bear the burden of witnessing the tragedy firsthand as it has developed.
"And we remember everyone who feels helpless and shaken by what has happened here in Creeslough, as well as everyone else in Ireland and beyond."
"Over the last couple of days as people gathered in groups to discuss what has happened here these last few days, the one word that jumps out for me in reference to the explosion is something somebody said," the Bishop of Raphoe stated.
They stated it was extremely random. And she meant to say that anyone may have become involved in that. The things that life can and does throw up are profoundly frightening and unpleasant.
"Why did they have to be there at that awful moment?," he said.
"The terrible insecurity of that subject must be carried by the deceased and the injured. Others among us might easily harbour some guilt.
Why was it them and not me who was struck by the tragedy's arbitrary nature? Fundamentally, it is a painful realisation that we are not in control of our own fate.
“We are very fragile, all of us, fragile and vulnerable.”
Ten red candles have been lit inside St Michael's Church in tribute to those who lost their lives in the explosion.

Creeslough commemorates the victims of the blast
He stated, "The thoughts and prayers of the nation are with the people here," late on Saturday during a visit to the community.
Government assistance will be available both now and in the future because it can take a community a very long time to recover from something like this.
Creeslough is situated in the north-west of Ireland and has a population of about 400 people.
Taoiseach (Irish Prime Minister) Micheál Martin said the nation was in mourning after the explosion. He spoke to members of the emergency services who had worked for 24 hours to find the victims.
