1. They like to hear and recite Sanskrit slokas.
2. There is a longing in them to be part of a greater tradition which  has substance. They indirectly accept that Hindu tradition is the oldest and has great depth.
3. There is a paucity scriptures in  Christianity. They do not mind making the Hindu Vedas their own.  Remember they have adopted the Jewish Talmud and made it the old  Testament.
4. It is evident that they still look up to the  Hindu Brahmanism. That is why they would like to call themselves  Christian Brahmins.
5. Even though they ‘poo poo’the Karma theory, they love reciting ‘Punarapi Maranam, punarapi Janani jatare sayanam.’
6. Usually the Christian ethos will be proved by using Bible quotes. In this movie the Hindu Sanskrit quotations are being used to prove that  Jesus is the only Saviour of mankind. They don’t realize that the same  quotation may be used to prove Satan too.
7. They have deep  respect for Vedas and Upanishads. They also have lot o respect for Adi  Shankarar and Vivekananda though their teachings are twisted.
8. Their Mantra for other religions is “Any religion is acceptable,  since all are the same”. But the mantra for themselves “only Christ,  only Christianity and only Bible”. This exposes their hypocrisy.
Why then convert and revere a foreign God, a foreign Religion and foreign land?
