All of us here have experienced how two-faced Watchtower is. Yes it pretends to be Christian but they are not.
Genuine charity and sharing is a fundamental Christian value:
(Acts 2:44) . . .All those who became believers were together in having all things in common,
(Matthew 6:3-4) . . .But you, when making gifts of mercy, do not let your left hand know what your right is doing, 4 that your gifts of mercy may be in secret; then your Father who is looking on in secret will repay you. . .
That said, I remember an African sister telling me how two-faced a Catholic priest in Africa was. She explained to me that the British would send their clothes off for charity but when they reached her part of Africa they ended up in the hands of a priest who would only give the clothes away in return for an act of prostitution.
I have no detailed facts for this story, therefore I cannot assess how true it is. But I can imagine such senarios taking place (not only with clothes but also with food) in both secular and religious settings where people are being two-faced.
