Grace was being shared when the first shot rang out. For dozens of worshippers at the St Francis Catholic Church in Owo, south-western Nigeria, the Lord’s prayer turned into a viaticum – the final prayer.
The armed men that burst through the church doors around 11:30 on Sunday set off dynamite that had congregants scampering to escape the explosions.
As worshipers rushed for the other two exits in the chaos, they were met by more armed men, followed by more shots and loud bangs.
At the end, eyewitnesses say at least 50 bodies – some of them children – were left strewn across the church floors, while many more were injured.
There was blood on the altar, blood on the floor, bodies on the pews.
It is still not clear how many people have died and or were injured. But the Bishop of the Catholic Diocese of Ondo says the church, which is one of the biggest parishes in Ondo state, can hold up to 1,200 people. It was full at the time of the attack.
“They killed to their satisfaction before leaving,” chorister John Nwovu told the BBC.
He hid in the sacristy with others while the attack – which lasted for around 30 minutes – was going on and said he was only saved by God’s grace.
An explosion blew up the ceiling above him, burying him and several others, he said.
They bore the weight and pain in silence while the killers went about, picking off worshippers hiding under the pews.
Mr Nwovu’s brother, also a chorister, was shot in the leg and is recovering in hospital.
“I don’t think the shock of what I saw will leave me for the rest of my life,” he said.
Dynamite residue still litters the church, while the vestry – where many hid – bears testimony to the chaos.
Shoes, bible pages soaked in blood, purses and other personal belongings are still scattered about.
For members of this quiet community in Ondo state, the church was more than a place of worship – it has been a part of their lives since birth.
This was a surprise attack. Owo is relatively peaceful and has been spared the wanton killings that seem to happen weekly across Nigeria.
Attacks on churches have happened before – it was a tactic of Islamist militant group Boko Haram, but the gruesomeness of this attack has shocked many.
This was a congregation of the aged and the very young. Worshippers had turned up in their Sunday best for the Pentecost service, which marks the birth of the church and official end of the Easter season.
“I saw entire families being wiped away, friends, relatives, those I knew,” said Mr Nwovu.
For orthodox Nigerian Christians, first Sundays of the month are also significant. They are usually full of colourful thanksgivings led by families and parish groups and this would have been no different.
Folake Oni, 56, doesn’t remember how she survived the attack. She only recalls exiting the church and being taken to hospital.
Her daughter Elizabeth Ademiluka told the BBC that her mother was traumatized but physically well.
On Monday, a sombre mood engulfed the town, with hundreds of anxious people at the hospitals and dozens more at the church.
People are walking about with a blank stare, wondering how their lives have changed forever.
There is still a crowd at two local hospitals where volunteers rushed to donate blood after the attack.
But more is still needed, said Nigeria’s medical association, which has urged people to donate more at local hospitals.
Everyone seems to know someone inside the hospital where many are critically injured and some are fighting for their lives.
Many of the survivors at the Federal Medical Centre (FMC) in Owo have been shot in both legs, some might never walk again.
There is a palpable outrage, plenty of which has spilled onto social media, where people followed the attack with shock as it happened.
The pictures are too gory for many Nigerians, even those numbed by the numerous deaths witnessed in the country.
Some of the children killed were unrecognisable – the high-calibre bullets scattered flesh and bones, a medical worker at the FMC told the BBC.
“The audacity of Nigeria to take my parents from me. I will always hate this country!!!!! It’s a promise!,” said one Twitter user.
The outrage over the killings has been further exacerbated by pictures of President Muhammadu Buhari, Vice-President Yemi Osinbajo and other members of the ruling All Progressives Congress (APC) eating at a state dinner hosted by the president, hours after the attack.
In one of the pictures, the politicians dressed in colourful robes are smiling. A convention to elect the party’s presidential candidate for next year’s general elections is underway in Abuja.
