The problem is, as in most cases concerning Catholic theology, is a failure to DISTINGUISH. One must distinguish between 1) the mass and 2) the sacrament of the eucharist.
The mass is composed of 3 parts - offertory, canon, communion - which make up the sacrificial rite. At a new 'mass', the canon/consecration COULD be valid, while the Mass, overall, IS NOT, because there is no sacrifice, as is understood by catholic theology.
The 'sacrifice' as, heretically taught by V2, is Christ's offering of Himself in Holy Communion at the Last Supper; the REAL sacrifice of Calvary/Good Friday is nowhere mentioned in the new 'mass'. Hence it is not a mass which is why it is "odious in God's sight" (MARIE-JULIE JAHENNY visions).
To sum up, it's possible to receive Our Lord at the new 'mass' provided the consecration is valid. Therefore, it's possible that the eucharistic miracles are true, in that Our Lord allows those who still have some Faith to see, but these miracles do not change the facts that
1) the new 'mass' is not a mass. Therefore, God is not properly adored, thanked, petitioned and asked forgiveness for sin.
2) V2 and the new 'mass' teach a new theology and faith. They cause people to lose the Faith and go to hell.
3) the new 'mass', in many cases, is NOT valid and is a circus act. This is a blesphemy, sacrilege and highly offensive sin against God and heaven.
Humanly speaking, we might say, "Oh, God is present during that ceremony, so that's good." God would say, "I have allowed Myself to be present for those few who still believe. But, in this unholy atmosphere, I am reliving My passion, for I am mocked, blasphemed and forgotten, and it's worse than at Calvary, for it happens from My own people, by My own ministers, in My own house. They honor Me with their lips, but their hearts are far from Me."
