A Samuel has no right to ask the Vanvasi Kalyan Ashram to leave Jharkhand unless he himself has evacuated his whole army of missionaries from Jharkhand. There are tribals having the names of Hindu Gods and Goddesses like your own Shibu Soren which is the name of lord Shiva, Ganeshram Bhagat, Mahendra Karma in Chhattisgarh. Tribals are very much Hindus. Let's assume for a while that tribals are not Hindus and they are converted to Hinduism. In such condition also the tribal will be getting the Indian Gods and Goddesses not an imported God called Jesus. We do not want any imported religion or gods. Even Ambedkar did not accept a foreign God and opted for a native Indian God- Buddha.
