Zechariah 14:21

Yea, every pot in Jerusalem and in Judah shall be holiness unto the Lord of hosts, all the distinctions of the Ceremonial Law being eliminated; and all they that sacrifice shall come and take of them and seethe therein, preparing for the sacrificial feasts without fear of contamination; and in that day there shall be no more the Canaanite in the house of the Lord of hosts, no openly godless people being permitted as members of the Church of God. The nearer the Church approaches its perfection, the clearer is shown the cleavage between those who are in truth the servants of the Lord and those who merely bear the name of His ministers; and the final revelation of those who in the accepted time, in the day of salvation, were for and against the Lord Jehovah will conic on the Last Day.
