Seraphin was austere in his person. Only once in his life did he accept a new religious habit, and then, only out of obedience. For forty continuous years, he ate only soup or salad. In keeping with the spirituality prevalent at the time, Seraphin had a personal devotion of serving as many Masses as possible. To avoid having people kiss his hand or tunic to show their respect, Seraphin would carry a crucifix with him, offering it for them to kiss instead.
