You also, as living stones, are built up as a spiritual house, to be a holy priesthood, to offer up spiritual sacrifices, acceptable to God through Jesus Christ.
Are built up a spiritual house ...  It is important to note that house here bears its ecclesiastical sense of temple.  Jesus himself used the word in that same sense when he declared, "Behold your house is left unto you desolate"  (Matthew 23:38).  In this statement, Peter gave the same teaching that Paul gave, who said, "Ye are a temple of God"  (1 Corinthians 3:16f), and "being built upon the foundation of the apostles and prophets, Christ Jesus himself being the chief corner stone"  (Ephesians 3:20).
