“Sacramental Theology After Pope Francis’ Encyclical Laudato Si.”

Care of Our Common Home

On Pentecost Sunday 2015 Pope Francis issued his only encyclical to date entitled Laudato Si . On Care for Our Common Home. Among several things the pope addresses is the importance of education on ecology drawn from the Catholic tradition and the way that human persons and fellow creatures in our common home are engaged in the church’s acts of liturgy and sacrament. In this lecture Msgr. Irwin will draw on these fundamental insights and offer a way of understanding the study and celebration of liturgy and sacraments in light of Laudato Si.


Open to the public. Reception to follow.
