His reflections connected the congregation's present celebration with its historical roots and challenged the current generation to remain faithful to the missionary heritage entrusted to them.

Remembering the Founders

The Jubilee was also an important moment to honor the founders of the congregation, Bishop Sisto Mazzoldi and Very Rev. Fr. John Marengoni, whose missionary vision and dedication contributed to the establishment of the congregation.

The Congregation also celebrated with gratitude to remember the pioneers whose courage, faith and missionary commitment helped shape the congregation's journey.

For the Superior General, the Golden Jubilee was not merely a celebration of fifty years but a moment to recognize God's faithfulness throughout the congregation's history.

Silver Jubilee Celebration
