It all depends on whether you consider Mr. Ravi Krishna to be a Christian or a Hindu.
I believe he is a Christian, because his mother is Christian.
Irrespective of what we believe, it is important what the temple believes. As per the religious rules there, the children inherit the religion of their mother, not father.
Finally, there is enough information there, that the family practises Christianity. Mr. Vayalar Ravi tried to cover it up in his interview yesterday, by saying that their family if "progressive and secular". Please read his interview published in Rediff yesterday.
