Men add their own commandments to churches and cause the congregations to sin

Dr. Joan Boney, Jesus Ministries ...

Unless God authors the plan, it is sin.  Men often try to do something that seems religious to them and they set up religious requirements for the congregations and often those rules cause the congregation to sin.  

Paul explains this in the following:  Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils ... Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth. ( I Tim. 4:1;3)

Therefore "idols" are set up in their churches for people to worship by doing these things not commanded by God.
