If you’re a disciple of Christ who follows and obeys His teaching, then this is something you ought to think through. I did some searching and there seems to be mixed opinions on this topic. The people (we’re talking about Christians here) that are into art or study art seem to understand the importance of studying the human body and so they are “for it.” On the other hand, the non-artists seem to be opposing it at all cost. My suggestion is first read the articles that I’m about to link so you can get an overall perspective on this important topic and then examine your own heart and seek the Lord for understanding.
Fine Art will help you to grow as an artist and that involves the studying of human anatomy, the naked body. So the question is: Is it a sin to look at nude model(s) or images to better our understanding of it so that we can recreate it with realism? Let me start off by saying that as of this writing, I do not take a “for” or “against” position simply because it’s not black and white. On the practical side of thing, I can only speak for myself after having examined my own heart. I can not come to you and recommend that you go and study nude simply because I don’t know you and the things you struggle with. It’s the same reason they don’t serve real wine in most churches when it comes to the Lord’s Supper. Take for example: I don’t watch pornography, and I stay away from it (by the grace of God). And the images I collect for my studies are not pornographic in nature. If done right it can aid you in your studies, but if done wrong it can become a stumblingblock. As believers, we have to be extremely careful and also keep in mind that the heart is very deceitful. Do you have a passion to grow as an artist or do you use Fine Art as an excuse to lust after the female body and to collect pornographic materials all in the name of “art”? Search your heart and be honest. God knows. If you struggle with lust and are easily triggered, then perhaps Fine Art isn’t something you should be pursuing, though you can still do art!
There are Christian colleges which allow drawing of the human figure clothed in bikinis or racing suits both of which resemble underwear and have well known advertising campaigns associated with them that exploit sex as the main point of their style. This practice seems inappropriate and more sensual by its suggestive commercial context and the unnecessary focus upon the covered area that it invites. To some, it appears more like going to the beach than to the classroom where serious academic study is underway. (Gordon College’s Policy on the use of Nude Models in Art)
The Greeks believed that man was the measure of all things; as such they sought to find the perfect human form and show it in their art. The resulting nudes are not pornographic; rather, they are the outworking of the Greek ideal. As Christians, we rightly reject their philosophy, but we should not make the mistake of mislabeling their art. (A Christian Perspective on Nudity in Art — Matthew Clark)
I remember coming across one YouTube video made for fine artists but had to turn away because it wasn’t done right and was very inappropriate. Just because it says “for artists” doesn’t mean that it’s right and appropriate for Christian artists.
