As you consider the Catholic Church is made up of saints and sinners, I feel that the Catholic Church has contributed significantly to society (hospitals, universities, St Vincent de Paul Society, etc) with the teachings of Jesus and showing us the way to Heaven.
Perhaps we don’t need the curing of the sick and the raising of the dead as Jesus and the Apostles did. Our mission is to teach and baptize so that all will join God in Heaven. That is the true miracle. Yes much work needs to be done. Actually, I believe there is significant curing of disease through prayer that is just not reported.
The greatest miracle is our ability to receive God in the Holy Eucharist.
