The Ritus Servandus section of the Roman Missal contains an outline of the rubrics for the celebrant at Low Mass and sung Masses (missa cantata), as well as for Solemn High Mass for the celebrant, deacon, subdeacon and some points about the inferior ministers (servers). Even rubrics related to Mass offered pontifically and in the presence of a prelate are included.

The Ritus Servandus booklet takes the reader from the initial preparations of Mass through its various parts, and includes two appendixes:

• on the vesting prayers of the celebrant,
• and from Rituale Romanum on the "The Rite of Blessing and Sprinkling Holy Water on Sundays".
