Good question. I don't know about blasphemous exactly but if a person's a true Christian who follows the bible (that says not to get tattoos I believe) wouldn't it be at least hypocritical? I'm not a bible scholar, I guess I'm just answering your question with another question.
No ,because to have a tattoo you have to feel passionate about it and I have to have tattoos done that I can connect with spiritually or personally.<br />
It's a permanent thing so you have to have respect for what you get done,it has to mean something to you,so how can it be blasphemous?
Well almost anything can be considered blasphemous depending on the person and the religion.
