The Bishop of the Wollongong Diocese, Reveren Brian Mascord, has welcomed the appointment of Pope Leo XIV as a "sacred and historic moment" for the Catholic Church.

Robert Francis Prevost, a 69-year-old who was born in Chicago, has been announced as the successor to Pope Francis, who died on Easter Monday at the age of 88.

Reverend Mascord on Friday described the appointment as one that will continue to guide Catholics on their spiritual journey and build upon the legacy of Pope Francis.

"This is a sacred and historic moment for the universal Church and fills our hearts with renewed hope and calls us to unity as one body in Christ," Reverend Mascord said.

"The election of our new Holy Father comes at a time of both challenge and opportunity.

"Guided by prayerful discernment and trust in God’s providence, the cardinals have chosen a man who brings with him a deep love for Christ and his Church, a commitment to the Gospel, and a heart for humility, service, and evangelisation.

In his first address, Pope Leo XIV calls us to renewed discipleship when he proclaimed that 'The world needs Christ’s light. Humanity needs him to be the bridge so that God and his love can reach us'.

"As Pope Leo XIV begins his petrine ministry, I invite all the faithful of our diocese to unite with me in prayer for him. May he be granted wisdom, courage, and strength to shepherd the Church with compassion and truth."

Reverend Mascord said this new chapter of the Church’s journey would renew their commitment to faith, discipleship, and unity.
