Final answer:
The process for canonization in the Roman Catholic Church involves several steps, including beatification and the examination of miracles. Both Dorothy Day and Thomas Merton have made significant contributions, but whether they should be declared saints is up to the Church to decide.
Step-by-step explanation:
In the Roman Catholic Church, the process for canonization, or declaring someone a saint, involves several steps. First, a person must be declared a Servant of God, and then a Venerable. After that, evidence of miracles attributed to the person's intercession is examined, and if deemed authentic, they can be beatified. Finally, another miracle is required for the person to be canonized, or officially declared a saint.
In my view, both Dorothy Day and Thomas Merton have made significant contributions to the Church and society. Day was a prominent social activist and Merton a renowned theologian and writer. Both have inspired many with their dedication to issues of justice and spirituality. However, whether they should be declared saints is ultimately a decision for the Church to make, based on the examination of their lives and miracles attributed to their intercession.
