Gandhi opposed Christian missions that courted Untouchables for conversion without aid

Evidence

It hurt me to find Christian bodies vying with the Muslims and Sikhs in trying to add to the numbers of their fold. It seemed to me an ugly performance and a travesty of religion. They even proceeded to enter into secret conclaves with Dr Ambedkar. I should have understood and appreciated your prayers for the Harijans, but instead you made an appeal to those who had not even the mind and intelligence to understand what you talked; they have certainly not the intelligence to distinguish between Jesus and Mohammed and Nanak and so on … If Christians want to associate themselves with this reform movement they should do so without any idea of conversion. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 421
