Do you even know the difference between claiming to be reformed due to being part of a Reformed churches, versus being reformed in putting off Roman traditions of men? Thus i said you are not reformed enough.
Many congregations in the Christian Reformed Church today observe Ash Wednesday and Lent - which in times past they repressed - and other days of Rome's liturgical "days, months, times and years," as are many Baptists, moving closer to Rome.
I’m not CRC nor have I ever been nor will I ever be due to significant doctrinal differences. At heart I’m reformed presbyterian, though I’m a member of the free reformed church.
The problem here is that you seem to believe the Old Testament and New Testament are entirely different when in fact the New only confirms what the Old told us would happen. The old covenant isn’t different from the new covenant, it is only extended beyond Israel. It changes from circumcision to baptism because we no longer need the symbolic blood, our one and only saving blood is Christ’s.
Acts 2:38-39 confirms this position when Peter commands new believers to be baptized. He stated clearly that the promises made by God via baptism were not only for believers but for their children also. This is no different than the old covenant, wherein God commanded Abraham to circumcise himself and his entire household. Keep in mind when the Jews that Peter was speaking to heard him reference promises made to believers and their children they would have instantly recognized the connection between baptism and circumcision.
In Acts 16:15 Lydia and her household were baptized. In Acts 16:33 the Philippian jailer and all his family were baptized. In 1 Cor 1:16 Paul tells us that the household of Stephanas was baptized. This mirrors Genesis 17 which taught that Abraham’s household was circumcised. In other words, the entire family was baptized in the New Covenant and circumcised in the Old Covenant. This includes, obviously, children.
In addition, Christ admonishes those that would keep children from him in Mark 10:15-16. Those who deny the children of believers a place in the covenant are specifically violating Christ’s command.
