What do you mean by
Old Testament superstition?

We mean the foolish and heretical notion that there is residual value of any kind in Jewish ordinances from Moses and Mt. Sinai e.g. tabernacle furniture, the Sabbath, infant baptism, etc. Satan has mounted for nearly 2000 years a comprehensive campaign to dishonor Jesus Christ and redirect and distract Bible believers from the better covenant, ordinances, and promises of the New Testament. We stand rigorously opposed to any backsliding to Moses’ beggarly religion.
