I do have problems with it, and prefer to stick to what Scripture explicitly says about Mary. I believe it is explicit that she had other children. Some people disagree. I'm fine with that. I consider her as mother of other children a matter of interpretation. I consider her sinlessness anti-Scriptural. Her perpetual virginity, I consider a violation of the EWS, Until, but others disagree.
Mary with any titles of Christ, I object to. She is depicted in Scripture as Mother of Jesus and blessed among women. That's where I stand with Mary.
Others familiar with the language in question disagree.
