Let's not bring the Church in this. seiko is a decent chap and criticism or skepticism on his part in this matter does not necessarily mean he has ulterior motives.
Good that you are issuing him a character certificate but why double standards for the Church and Hindu Mahasabha ? .......... if he has no ulterior motive why drag in Hindu Mahasabha into this discussion ?
When you felt no qualms about him talking about Hindu Mahasabha, why this sudden concern when Church is mentioned ?
