The lack of charity was the principal reason my father balked at being a good Witness. While he was at Bethel, he had a chance to roam New York in his off time. He saw other church groups helping people with every day problems, such as food, housing, and emotional support. He even argued a bit while at Bethel that the Witnesses could start a small scale program in the local KHs so those in need had help. Within the Witnesses, such help is ad hoc. A lot depends upon the makeup of the congregation. After the WTBTS gets its take, not much is left in the way of resources.
This is in sharp contract to Jesus' express words about what you do for the least of humans, you do for me. Some individual Witnesses are charitable. Most churches devote a percentage of their income to charitable works. Jesus talked about charity to strangers yet my father thought all active Witnesses should have a family in the Witnesses.
I've volunteered in homeless shelters, AIDS ministries, and food kitchens. The volunteers receive a tangible benefit from helping others. First, you feel better that at least something is being done. Second, you are able to meet people outside your comfort zone. The atmosphere in these program is usually one of loving service. Third, it presents opportunites to socialize and bond with other Christians. The largest AIDS charity in New York during the height of the AIDS crisis, God's Love We Deliver, became the hottest singles place.
What threatens the WTBTS so that it prevents organized charity? Elaine Pagels, the New Testament and Gnostics scholar, wrote that the earliest Christians had the sermon open to the general public but communion was available only to those baptized. The nonbaptized were forced to leave the premises before communion. Outsiders heard talk of the body and blood of Christ being present and also noted that Christians called each other brother and sister. They assumed cannabilism and incenst were happening. Therefore, the earliest crimes Christians were accused of commiting were crimes aginst humanity. The Church responded by allowing nonbaptized persons to witness the Eucharist. Not much later, plagues hit many Roman provinces. The Christians were unlike other religious groups. They did not flee. Rather, they felt a duty to remain and nursed even nonChristian victims back to health. They buried the dead. These acts were a turning point in Christian and nonChristian relations.
It was a more powerful witness concerning the Christian beliefs than attending meetings and knocking on doors.
