Stuyver was ordained a priest by Bishop Robert Fidelis McKenna, O.P., in 1996. On January 16, 2002, McKenna consecrated Stuyver to the episcopate at the IMBC's St. Peter Martyr Seminary at Verrua Savoia near Turin, Italy. Frs. Francesco Ricossa and Joseph Selway assisted as altar-servers. Stuyver is the superior of a community of the Institute at Dendermonde, Belgium. Prior to the consecration of Stuvyer, the Institute relied on McKenna and his associate, the Sedevacantist bishop Oliver Oravec, for ordinations. Stuyver was consecrated to relieve them of these duties.
