On my way home this evening, I passed a church building that had a sign posted out front stating their times of service. Not only that, it also stated the type of service that it would be; informal, contemporary, or traditional. My question is, where do they get the athuority to change the worship service other than to do what was commanded of us in the Bible? God set certain rules for us to follow, and if we don't follow them, aren't we guilty of itching ears? (See Tim 4: 2-4) Many people pose the argument that "Well, society changes and we just want to bring the people in the door." So people presume that they can bring God down to the level of society instead of bringing people to God with truth as He commanded.
God doesn't change, so why should our worship to Him have to?
Hebrews 6: 17-20
Because God wanted to make the unchanging nature of his purpose very clear to the heirs of what was promised, he confirmed it with an oath. 18God did this so that, by two unchangeable things in which it is impossible for God to lie, we who have fled to take hold of the hope offered to us may be greatly encouraged. 19We have this hope as an anchor for the soul, firm and secure. It enters the inner sanctuary behind the curtain, 20where Jesus, who went before us, has entered on our behalf. He has become a high priest forever, in the order of Melchizedek.
He didn't say that if you change and have 3 different types of services that you are OK. So who has the authority to say that these forms of worship are acceptable?
