Matthew 3:22-25 And the teachers of the law who came down from Jerusalem said, “He is possessed by Beelzebul! By the prince of demons he is driving out demons.” So Jesus called them over to him and began to speak to them in parables: “How can Satan drive out Satan? If a kingdom is divided against itself, that kingdom cannot stand. And if Satan opposes himself and is divided, he cannot stand; his end has come.
God always do good while Satan does the opposite. In the scripture above, the teachers of the law accused Christ of doing the devil's work by HEALING a person possessed by demons. It is already clear that this kind of thinking does not make any sense. How can healing be considered evil? Satan would never heal a person by driving out demons. It goes against the nature of Satan to do that.
While some accused the Neocatechumenal Way of being evil, evidence shows that some marriages have been saved, that some families and itinerants have given up everything to go on mission for Christ, that vocations into the priesthood and convents have been inspired among its members, and that the youth remain active in participating in World Youth Day pilgrimages.
The NCW have also built up their parishes through volunteer work. If one were to visit the parish, one would find some members of the NCW serving as lectors, Eucharistic ministers, altar servers, CCD instructors and coordinators. Some of them were elected into parish councils and have helped the parish in various ways. Some have even volunteered their service in the parish choir and in maintaining and cleaning the parish grounds. Others have donated time and money in renovating the parishes and donating flowers for the Church. All these were done without any cost to the parish. All these were done as a result of the brother's desire to serve God and His Church.
This volunteer work is also found in the NCW itself. There are no rules of forming a Catechist, Responsible, and Co-responsible in the NCW. It was all done with the person's desire and zeal to volunteer their service to God. It was done with a "yes" response after they were asked to become a Catechist, Responsible, or Co-responsible in the Way. Missionary work was also done voluntarily. Sometimes, the person who volunteered to do a service without pay and with only their desire and zeal can turn out to be a better volunteer than one who was paid to do the job and holding a degree.
