Q: Who says “Mysterium fidei” during Mass, especially when a bishop is the principal celebrant and assisted by several priests? Does a priest take the role of a deacon in announcing “Offerte vobis pacem” and “Ita, missa est”? If the three are roles of a concelebrating priest when a bishop is the president of the liturgy, kindly provide liturgical documents that will help me explain it well to others. -- R.P., Kasama, Zambia
