The Roman Catholic Mass is obsolete -- a religious act of futility. Jesus' sacrifice on the cross was once and forever! No further sacrifice is needed!
11 And every [Roman Catholic] priest stands ministering daily and offering repeatedly the same sacrifices, which can never take away sins. 12 But this Man, after He [Jesus] had offered one sacrifice for sins forever, sat down at the right hand of God, 13 from that time waiting till His enemies are made His footstool. 14 For by one offering He [Jesus] has perfected forever those who are being sanctified.
15 But the Holy Spirit also witnesses to us; for after He had said before,
16 “This is the covenant that I will make with them after those days, says the Lord: I will put My laws into their hearts, and in their minds I will write them,”17 then He adds, “Their sins and their lawless deeds I will remember no more.”18 Now where there is remission of these, there is no longer an offering for sin.

The Roman Catholic Church teaches that Jesus was a victim on the cross and by extension a victim in the sacrifice of the Mass (though they claim it's the same sacrifice and not a re-sacrifice). "Jesus on the Cross is the Lamb of God, both priest and victim, in a new passover sacrifice whereby the whole world is redeemed from sin and death." 1
According to the Bible, Jesus was not a victim. He willingly suffered and died. 17 “Therefore My Father loves Me, because I lay down My life that I may take it again.18 No one takes it from Me, but I lay it down of Myself. I have power to lay it down, and I have power to take it again. This command I have received from My Father.” (John 10:17-18) See: The Victim's Victory by Cameron Buettel (GTY Blog) http://www.gty.org/blog/B160325
The Roman Catholic Church calls the Mass the "unbloody" sacrifice of Christ. 2 The Council of Trent declared that the Mass is an actual sacrifice for sins and if anyone says that it is not, let him be anathema. (Trent: On the Sacrifice of the Mass: Canon 3)
The Bible says without the shedding of blood there is no remission for sins. "And according to the law almost all things are purified with blood, and without shedding of blood there is no remission." (Hebrews 9:22)
Again, the Roman Catholic Mass is a religious act of futility at best and a blasphemy against God at worst!

Supposed “eucharistic miracles” are often pointed to by Roman Catholics as evidence for the “real presence” and/or transubstantiation in the Eucharist. Most of the claimed eucharistic miracles involved one or both of the elements miraculously being turned into literal blood or literal human flesh. Some of the reputed events are as follows...
