The three-day symposium will begin with an introduction from Pope Francis on faith and the priesthood today.
Around 500 priests, bishops, religious, and other Catholics are expected to attend.
The sessions will be chaired by the heads of dicasteries in the Roman Curia, while Cardinal Kurt Koch, president of the Vatican’s Christian unity council, will also be a featured speaker.
Theologians and other Catholic experts will present on topics including the Fathers of the Church, St. Thomas Aquinas, priestly celibacy, the pastoral challenges of the priesthood, vocational formation, and the complementarity of the different states of life.
A roundtable on women and ministry will take place on the second day, Feb. 18.
The symposium on vocations will be one of the first Vatican conferences to be held in-person since the start of the COVID-19 pandemic.
Cardinal Ouellet told Vatican News on Wednesday that the conference will address the “fundamental priesthood of the baptized and the ministerial priesthood.”
“Usually, when we think of priesthood we think of the priests and bishops and so on, but the fundamental priesthood is the priesthood of the baptized: we are part of the Body of Christ and as such, we participate in the mediation of the Church, the participation of the Church in the Priesthood of Christ,” he said.
Ouellet also explained that while priestly celibacy will be a topic at the symposium, it is not within the conference’s scope “to decide whether we will keep obligatory celibacy or not.”
Other speakers at the event will include French theologian and Dominican priest Father Serge-Thomas Bonino, German biblical scholar Robert Vorholt, Italian theologian Father Piero Coda, and French theologian and religious Sister Alexandra Diriart.
