Who is Really the Master Behind the Veil?

Born again Christians will stop believing christmas, halloween and easter because they acknowledge that these tradition are not biblical. It will cost nothing for any Christians if they amend their beliefs by removing these tradition practice in their belief system. But, it's difficult in TITHING even though they are aware that biblically it was cancelled and will even defend its doctrine without the use of biblical support. Why? because for so long that tithing is being practice, it became the lifeblood of the church, the leaders, the ministers fear that if they stop requiring the congregation to tithe rather give what the heart desires, the church might eventually not stand because, they worry on how would they able to maintain the payment of the bills, the rental cost, etc, if there are no assurance (by means of planting fear using Malachi 3:10) from the congregation that there will be a steady cashflow of money into the church. And, Pastors or Ministers that get their maintenance from the Gospel might not able or would worry how will they able to support their family (see link: Pastor Right to Live by the Gospel). Ironic that, the same Leaders, Pastors and Ministers believe that they serve a God who can make all thing possible yet, worries such a thing.

The bible said;

“No one can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon.”Matthew 6:24 NKJV

It made me wonder, if tithing became the life blood of the church even though there is no biblical support that, it's allowed to practice in the dispensation of grace in fact it was cancelled in Hebrews 7:18 but then, pastors, leaders are afraid that the church might not stand if they stop requiring the congregation to tithe. Who is really the master behind the veil? Money or God?
