Pope Francis has ruled against ordaining married men in the Amazon region as a means of addressing the shortage of Catholic priests.
Bishops backed the measure last year, but the decision needed the Pope's approval to be implemented.
Catholic priests are required to abide by the rule of celibacy upon ordination except in cases where married Anglican ministers have converted.
Celibacy is seen as the devotion of one's life to God.

The Pope said there was a need for ministers who can understand Amazonian sensibilities and cultures from within. He urged bishops to "promote prayer for priestly vocations" and to encourage those who want to become missionaries to "opt for the Amazon region".

But the conservative wing of the Catholic Church – particularly in Europe and North America – has spoken out against the idea, arguing that this could lead to the global abolition of celibacy.
Pope Francis had previously said he would consider the possibility of viri probati (men of proven faith) carrying out some duties.
"We have to give a thought to whether viri probati are a possibility," he told German newspaper Der Zeit.
Also on Wednesday, the Pope announced he had decided not to allow women to serve as deacons, a lower rank than priest.
Focus on climate change rather than celibacy'
It might be convenient to conclude that Pope Francis' decision not to accede to the request from Amazon bishops is a victory for his predecessor, Pope Emeritus Benedict XVI and those traditionalists who rRead More – Source
