How does the Church witness to Christ in the world? First and foremost by giving visibility to Jesus’ love for the poor and the weak. In a world so hungry for healing, forgiveness, reconciliation, and most of all unconditional love, the Church must alleviate that hunger through its ministry. Wherever we feed the hungry, clothe the naked, visit the lonely, listen to those who are rejected, and bring unity and peace to those who are divided, we proclaim the living Christ, whether we speak about him or not.
It is important that whatever we do and wherever we go, we remain in the Name of Jesus, who sent us. Outside his Name our ministry will lose its divine energy. – Henri Nouwen
I think Henri Nouwen may have been meditating on Matthew 25 when he wrote this.
