There is a very desperate evil spirit called antiChrist that has ‘Africanized’ the gospel of Christ in church by bringing in practices associated with ancestral worship, witchcraft and/or divination. Where have you seen ALTARS in the NT church in scripture? What does it say?

In Latin, “altare” is related to “adolere”, meaning “to burn up”.
In Greek, “thusiasterion” is the word commonly translated as altar in the New Testament and also in the Greek Old Testament which is called the Septuagint.  This word simply means “a place to sacrifice”.

An altar is a physical structure where sacrifices are burned.  In OT times the altar took on different forms & was used by many religions.  For Jews altars were used to sacrifice animals in obedience to God and burn incense on. Use of altars are in the law but was before the law.

The most important altar of all that supercedes all other altars & makes all other altars meaningless is the cross on which Jesus was sacrificed.  The  cross was God’s personal altar since He was the one who sacrificed Jesus.  In a sense, God sacrificed Himself as a man for man.

In NT when you see the Greek word for altar in it’s only in reference to OT Law and temple worship but also an altar found in Heaven.  In Matt. 5:23 - 24, 23:18, 20, 35 and Luke 11:51 Jesus uses this word in reference to the OT.
