first of all, welcome to the board! I moved this from the Serious Topics & Discussions sub-forum to the All Things Circa sub-forum. Not because I'm an ass but because we like to keep things tidy and organized around here to the best of our abilities. The mods are little mommies and daddies running around cleaning up after their children.
Anyway, I think you raise a very interesting topic of discussion and I'm sure we can all give you unbiased opinions of what we believe their stance may be.
Religion, particularly for the non-religious (myself included), do not love to discuss the topic of God and faith. If you were to ask any of the dudes what their positions are, they may choose to not discuss it with you. Spirituality is very private to me and I tend to internalize it so it's not something I speak freely about. It would appear that in Anthony's lyrics there exists some strife with "God". But, he could use God as a metaphor for other things. But I'll agree that even in songs like Kicking Your Crosses Down, it clearly appears that he has an issue with religion for one reason or another. Maybe it is the institution itself, maybe it's more personal. I think we can all relate that our parents raised us to worship a God or multiple Gods. Some continue in that path, others go in a different direction. Some feel betrayed or lead on, others just don't care. It's how they were raised and they were doing the only thing they knew how. His reasons are his reasons but I wouldn't call them "anti-religion". There are many beautiful things about religion that none of us can deny and it has brought good into this world. I think there are many that feel that the radically religious have caused a lot of hurt and harm and continue to do so. The band is anti-hate and they are extremely pacifistic, but not anti-religion.
For me, if I were to listen to a band that was very religious (ie: Mewithoutyou), it would only impact the way I appreciate and support their music based on how they "practice what they preach" or so to speak. Mewithoutyou is a fantastic band that has never made me feel threatened or offended by their beliefs. Others like For Today, for example, is a band I would never be able to support, even if I remotely enjoyed their music. To try to put myself in your position, I would tell you that this band has ONLY promoted love and acceptance and freedom to be who you are. The reason why Anthony does not typically discuss the meaning behind his lyrics is because he wants you to feel your own connection and find your own meaning. The songs don't have to be about God or religion. They can be about whatever is going on in your life and I think that's really special that he gives his fans the creative freedom in his music.
