"Hello an Taoiseach, this is the Vigil for Life, and I have 30,000 people here to give you a reminder of the pro-life promise you made in 2011," said Dr de Faoite.
To which the 30,000 strong crowd chorused "Enda, Keep Your Promise." The phone call followed more than an hour of speakers, crowd participation, and pro-life messaging at the Vigil.
The Vigil heard from one of Ireland's leading sports figures, Tyrone Gaelic Athletic Association county manager, Mickey Harte who said "I speak to you as an ordinary person, a citizen, a husband, a father. I come from a sporting background, as you know, and I am proud of our sporting traditions."
"But there is no tradition of which I am prouder than the respect for both women and their unborn children that has been the hallmark of our medical services in Ireland," he said. "Ireland, without abortion, is one of the safest countries in the world for a woman to be pregnant."
"There is no issue more important than the protection of human life. There's no point saving an economy if a child's right to life is compromised or forgotten," said the popular sports manager.
"The Vigil has been a tremendously powerful and historic event, and the voice of the majority has been heard for the protection of both mother and baby," said Eoghan de Faoite.
"We've reminded Fine Gael that abortion is not a treatment for suicide, and that the government needs to look at the evidence given before the Oireachtas Committee which confirms that fact," the Youth Defence spokesman said.
He added that the ban on abortion had made Ireland a safe place for both mothers and babies and that was something worth protecting.
A pro-life pledge which aims to sign up 100,000 people who say they will never vote for Fine Gael again if abortion is legalized, was also launched at the Vigil.
