I don't reject the use of a cross here and there or a picture of the tomb, etc. That is not the same thing as the command given to us in Exodus 20:4-5. The first part of the command simply tells us to not making any graven image in heaven above and the earth below, etc. This is in context to second half of the command that says not to bow down to such an image. In other words, who should you bow down to? God. So this command is saying not to make any images of God. It's not talking about crosses and or drawings of things that are not what we believe to be God. When people post pictures of Jesus, they are saying that this is God. Well, most people believe Jesus is God (like myself). So that is what they are saying when they post pictures of Jesus. They are saying.... "Hey look! This is my God!" That is what they are saying (whether they want that to happen or not). In other words, it is a lie. The picture is not really what Jesus looks like. A picture is merely a different form of communication than words. We are told not to lie in the Bible. So if we can lie with our words, we can most certainly lie with our pictures or artwork or images that we create or promote. We have to be true with everything that we do.
Actually, Romans 14 mentions NOTHING about creating or promoting images. It talks about our liberty in Christ in regards to what we can eat and on what day we choose to rest and worship God.
Also, Romans 14:21 says,
"It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak. " (Romans 14:21).
So if you believe Romans 14 extends to making idol images of our Lord (when it doesn't specifically say that), than this would mean that you should not approve of the open public display of them because they can lead others who are weak to stumble into idolatry.
