Matthew 9 10 While Jesus was having dinner at Matthew's house, many tax collectors and sinners came and ate with him and his disciples. 11 When the Pharisees saw this, they asked his disciples, "Why does your teacher eat with tax collectors and sinners?" 

Matthew 9 12 On hearing this, Jesus said, "It is not the healthy who need a doctor, but the sick. 13 But go and learn what this means: 'I desire mercy, not sacrifice.' For I have not come to call the righteous, but sinners."

“I desire mercy, not sacrifice.” Hosea 6:6 “I desire mercy, not sacrifice.”

Matthew 12 1 One Sabbath, Jesus was strolling with his disciples through a field of ripe grain. Hungry, the disciples were pulling off the heads of grain and munching on them. 2 Some Pharisees reported them to Jesus: "Your disciples are breaking the Sabbath rules!" 3 Jesus said, "Really?  

Didn't you ever read what David and his companions did when they were hungry, 4 how they entered the sanctuary and ate fresh bread off the altar, bread that no one but priests were allowed to eat? 5And didn't you ever read in God's Law that priests carrying out their Temple duties break Sabbath rules all the time and it's not held against them? 

6 "There is far more at stake here than religion 6 "There is far more at stake here than religion.7 If you had any idea what this Scripture meant – ‘I desire mercy, not sacrifice' - you wouldn't condemn the guiltless.

Matthew 4: Jesus calls his motley crew. Matthew 5: “Blessed are the merciful, for they will receive mercy.” Matthew 9: ‘Go learn what this means – “I desire mercy, not sacrifice.”’ Matthew 12: ‘If you had known what this means – “I desire mercy, not sacrifice” – you wouldn’t be doing what you are doing.’

“We associate ourselves together as a church of God under the name of the Church of the Nazarene. We seek the simplicity and the Pentecostal power of the primitive New Testament Church. The field of labor to which we feel especially called is in the neglected quarters of the cities and wherever also may be found waste places and souls seeking pardon and cleansing from sin. This work we aim to do through the agency of city missions, evangelistic services, house-to-house visitation, caring for the poor, comforting the dying. To this end we strive personally to walk with God and to incite others so to do.”
