Codex Monfortanius is proof for 1 John 5:7

In Monfortianus, its folio 87r's note says (speaking on Monfortianus, after Mark's ending)
English translation "it was wrote [written] ten centuries after Christ's acension"

Jesus ascended to heaven in the 30ADs (his ministry started at 30 years-Luke 3:23), & 30sAD+ten centuries [1,000 years]=a copy date in 1000sAD for when Monfortianus was written)+ 1 JOHN 5:7-8 IS IN THE TEXT!!

For those who claim Monfortianus is from 1500s instead of 1000s, the 1500s date is a false date as the 1500s' claimers did not see Monfort in person:
"Neither Michaélis nor Porson ever saw..Codex Montfortianus, which both yet dogmatically pronounce to be a MS. of the sixteenth century."  " 'A remarkable reading,
EYKAKEIV, Luke xviii. 1, is found in the MONFORTIANUS and ALEXANDRINUS [made in 300sAD), but no other.’
..this [is] one positive proof of the fidelity of..Codex Montfortianus,' "
