"The term the 'Holy Sacrifice of the Mass' came much, much later in church history."
Really?  The phrase, perhaps, but the Didache, written before the turn of the First Century, refers to the Eucharist as sacrifice as do both Clement (also in the First Century) and Justin Martyr, writing only 70 years later.
"When did Jesus present his Father that way?"
Matt. 20: 18-19 and 26:39, Mark 10:45, Luke 23:46.  Outside of the Gospel accounts there are numerous others from Scripture that further demonstrate the necessity of Jesus' sacrifice.
I do agree that statues, kneelers, are not constituent to the faith.
