During the Second Vatican Council (1962-65), the Catholic Church developed and approved a document that affirms the Christian vocation and participatory role of the laity in the Church’s mission of spreading the Gospel.
The decree Apostolicam Actuostatem (Latin for Apostolate of the Laity) was promulgated by Pope Paul VI on November 18, 1965, Pope Paul VI.

The document faults the erroneous thinking of Catholic sacerdotal superiority as it emphasises the collaborative, complementary and supportive relationship that must exist between the clergy and lay members of the Church, who also share in the priesthood of Jesus by virtue of their baptism.
This year, the Catholic Church commemorates 60 years of the promulgation of the Lay Apostolate Decree. As one of the activities of the celebration, the Catholic Bishops of Uganda, through their department of Lay Apostolate, organised a study workshop for the Church’s pastoral leaders, to help them understand and reflect more deeply on the message of the document, in regard to the role and shared responsibility of the priests, religious and laity in the Church.
The study conference took place at Ulrika Guest House, Kisubi (on Entebbe Road), in Wakiso district on November 17- 20 (2025).
It was officially opened by the Archbishop of Kampala Archdiocese, the Most Rev. Paul Ssemogerere, who also doubles as the Chairman of the Lay Apostolate Commission of the Uganda Episcopal Conference.
Delivering his homily, Archbishop Ssemogerere encouraged the Catholic faithful to work together to enhance the Church’s mission of evangelisation and social development.
He spoke highly of the decree, which he said promotes the values of synodality and co-responsibility, which must be practised by the members of the Church.

“Through Apostolicam Actuostatem, the laity are invited to give credible witness to Christ in all circumstances; on the streets, in workplaces and in society. They are to renew the church and society through their exemplary conduct and pious life. The decree encourages Christian formation. It is a call to action, a genuine conversion and a mission rooted in Christ. The Church needs Christian witnesses who put their heart, talent, leadership and fidelity to the mission of God,” Ssemogerere said.
Archbishop Dr Augustine Kasujja, Apostolic Nuncio, also put emphasis on the undisputable role of the laity in evangelisation as highlighted in the decree.
“Without the engagement of the laity, the Church advances abnormally, like a kangaroo. The people of God, I mean the clergy, the religious and the laity, must work in communion to overcome the challenges of evangelisation in the modern world.”
“The Uganda Martyrs are a perfect example of effective participation of the laity. When the pioneer missionaries fled to Tanzania due to persecution in 1882, Joseph Mukasa Balikuddembe and Andrew Kaggwa remained in charge of the Church. When the missionaries returned, after three years, the number of Catechumens had grown tremendously. Even in Madagascar, where I once worked as Nuncio, one lady and a religious brother once took charge of the Church. The beatified martyrs Daudi Okello and Jildo Irwa also ably maintained the presence of the Church in Northern Uganda.”
During the progression of the workshop, various presenters and discussants advocated the participatory role of the laity in the Church with even greater conviction. Those who gave interesting insights and testimonies include the Secretary General of the Uganda Episcopal Conference, Msgr. John Baptist Kauta, the Director of the Lay Apostolate Commission at Uganda Catholic Secretariat, Fr. Fredrick Tusingire, and the President of Uganda National Catholic Council of Lay Apostolate (UNCCLA), Gervase Ndyanabo.
