The early Christian named Justin Martyr wrote this in 151 A.D.?

I think we should mainly believe what the Bible says which is to remember His death and burial by taking communion. I dont however see anywhere in the Bible I have that says it turns to the literal blood and body of Christ when I take it. If it does thats ok too. Its totally up to Him and is not an issue with me. Is it you? His life comes into me as I believe on Jesus and His Spirit comes into me to live. It is His resurrection life.
