Wouldnt Messianic Christianity be useless to thous who are not Jewish, since in the NT while the Apostles were talking about the Gentile converts to Christianity, whether they should follow the Torah, the answer was no.
Useless? Maybe to some, but I've met many gentile believers who found the roots of their faith to be of value.
Everyone, please refrain from any debate on DIR forums, there are plenty of debate forums for that.
DIR forums are for fellowship and learning for those of that particular faith.
They may also be used by outsiders for asking genuine questions in a respectful manner without an agenda.
