Worshipers will line the roadside holding up their mobile telephones to light the way for Pope Francis when he arrives on his visit to Mexico next week.
The 79-year-old himself expressed “great happiness” at his looming visit, during which he will tour a major Catholic shrine in Mexico City and meet victims of violence and poverty.
Thousands of well-wishers are expected to come out to welcome the Argentine pontiff when he lands in Mexico City late on Friday. They want to make the longest ever human light chain on record.
They plan to line the 19km (12m) route from the airport to the Vatican’s diplomatic mission in the capital as the pontiff passes through in the Popemobile.
“We want to receive the Holy Father with a special wall, what we call a wall of light and prayer,” said Roberto Delgado, a member of the organising committee for the visit, on Sunday.
“We hope that with mobile phones, which are something that most people possess, we can make this light along the route the Holy Father will take,” he told a news conference.
Organisers played a video greeting from the pope himself.
“There is not long to go before my trip to Mexico and I am very happy. I feel great happiness. I have always had a special place in my prayers for all Mexicans,” he said.
The pope said he would fulfill one of his “greatest desires” by visiting the shrine of Our Lady of Guadalupe in Mexico City.
Organisers called on the faithful to bring rosary beads and pray for the pontiff as he passes along. They suggested bringing small electrical torches but no candles for safety reasons.
Delgado said they were aiming “to set a record by forming a human chain of light of 19kms (12 miles).”
“If people fill both lanes, then we are talking about practically 38 kilometers… That has never been done before in any country.”
The pope’s visit will run from 12 to 16 February and is scheduled to take in several Mexican states crippled by violence and poverty.
“I wish to come as a missionary of compassion and peace,” he said in the video.
His visit will include a mass in the city of Juarez, near the US border, plagued by violence and drug trafficking.
He will meet with indigenous peoples, prisoners and the families of victims of violence.
“I want to be as close to you as possible, but especially to those who suffer, to embrace them and tell them that Jesus loves them very much,” the pope said.
On the way to Mexico, the pope will stop over in Cuba for a historic meeting with the head of the Russian Orthodox Church.
