Medieval music includes solely vocal music, such as Gregorian chant and choral music (music for a group of singers), solely instrumental music, and music that uses both voices and instruments (typically with the instruments accompanying the voices). Gregorian chant was sung by monks during Catholic Mass.
A lesson that we can learn from the Feeding of the five thousand is that Jesus is big enough for any of our expectations. Here, He surpassed expectations. He is ultimate. This means that Jesus provides every need and He exceeds.
