Religion, and in this case the institution of Catholicism is the perfect tool - in this day and age, coupled with the social mobility of its adherents and those coming in from the outside, the believers are aplenty.
The "new" churches probably feature as another prong that has grown tremendously in influence because of the financial and social standing of their flock. Notice how Joseph Prince has now "re-emerged"/"resurrected" his ministry following the debacle with Kong Hee.
Faith is often absolute for believers (of any mainstream religious denomination) but the credibiliy of these new preachers is questionable and the Catholic Church is a representative of the Lord's Annointed Temple. The Catholic Church still has missions of local preachers who spend time abroad and some have gone to Jerusalem and returned quite traumatised not only at the behaviour of soldiers against Palestinians, but also towards Christians. But the significance is the concept of injustice and how brutal oppression of the less fortunate can be because of race and/or faith. Scroo' mention of Dr Ang made me rethink the proximity of good deeds and the Church and the players that seem to keep turning up in one guise or another (not suggesting that Dr Ang is anyway part of anything unsavoury).
As a side note, i am quite sure these missionary priests scoff at the likes of Joseph Prince standing on the steps at Jerusalem and proclaiming how the Kingdom is so great. Imagine the sermon on mount with the thickest Singkie/Malaysian accent.
It's the category of followers and church attendees that provides a much greater shield and probably the best Trojan front. In those circles I sense there are stirrings of displeasure at the direction of the country and the encroachment of parachuted yes-men. I've heard rumblings that the credibility of the new leaders of men is severely chastised and there is growing unease at who the ultimate successor for PM will be. Tharman is probably favoured but for obvious reasons cannot be the one.
So whatever shadowy elements may exist the sense remains that they will try and couple their agenda onto the wider sentiment that has grown amongst the faithful. There appear to be much more layered plans/agendas and the 2011 bad showing gave impetuous to the possibility of blindsighting the establishment because of overconfidence and apathy as serious issues that had hitherto been neglected were bandaged but not treated not acknowledged for their shortcomings.
Ultimately it's not the vulnerability of the Church but the flock - once they are turned then the direction can come from within as the believers will believe. It's a dangerous play given the delicate nature of inter-race cohesion and with the growth of Islamic fundamentalism in Malaysia and Indonesia there may be a reliance on that as a diversion from their groundswell.
