Bilbao, Spain: Fr. Séamus Finn, OMI Contributes to Global Dialogue on Faith & Finance May 8th, 2026
The Diocese of Bilbao, Spain hosted a Mensuram Bonam Conference for two days, an event that brought together nearly 70 diocesan treasurers, financial officers from religious congregations, and professionals in the field of ethical finance.
The event, held at Deusto Business School and the Diocesan Institute of Theology and Pastoral Studies, addressed a question that, according to the Bishop of Bilbao, Joseba Segura, “has been circulating for years regarding the financial management of many Church institutions : Are we investing in a way that is consistent with what we preach?”
Fr. Séamus Finn, an Oblate of Mary Immaculate and also a co-author of the Mensuram Bonam document, with almost fifty years of experience in faith-consistent investing in the United States, complemented Beccalli’s perspective with a more practical and pastoral dimension.
For Finn, the key to Mensuram Bonam lies in awakening a sense of responsibility: ” If you own shares in a company—Exxon, Iberdrola, any company—as an owner you have a responsibility. The document seeks to awaken people to that awareness .”
Finn also emphasized the importance of institutional transparency as a condition for credibility: “ People who support the Church with their donations must be able to understand that their money is being used responsibly .” He also expressed optimism regarding the progress made by the financial sector: “Many money managers have taken the document seriously because their clients are asking for it .”
