from the beginning, even as Jesus worked miracles right in front of them, many have refused to accept the teachings of Jesus.
many have tried to trade on the Gospel of Jesus Christ for their own self-aggrandizement.
many, having heard the Gospel, have rejected it and replaced it with their own, solely human (as opposed to divine) interpretations and understandings.
Jesus taught the apostles exactly what human life was about and its ultimate purpose/destination. Jesus is the only One who came down from heaven. all of the rest of us came in to existence at our physical conceptions.
those without faith in Jesus as the Incarnate Word do not understand any of this. when they participate in discussions, their lack of understanding becomes obvious.
most of those who try to place their own interpretations on Jesus while rejecting the actual teachings of Jesus also reject Jesus’ method for ensuring that the ignorant and vainglorious who would try to trade on His glory for their own benefits. that method is of course the magisterium Jesus created for the purpose of keeping the teachers of His Gospel faithful to it (the Gospel).
Jesus chose the Twelve to be the first magisterium of His Church. anyone who is trying to change what Jesus taught the Twelve is offending God.
we can only be confident in the teaching of the successors to the apostles, no other human beings have been given the gift of apostleship.
we are totally right to reject the understandings, visions, interpretations and practices of all who teach differently from the Lord’s magisterium.
we are not obligated to engage in discussion those mired in error. should they reject their errors, we are obligated to instruct them in the truth.
we can easily recognize those mired in error by observing their rejections of the successors to the apostles.
for those who ask, yes, God did suffer and die on the cross. God did shed His blood. that is the great mystery of the Incarnation.
st. paul the apostle, at least I think it was him, made it clear when he wrote, God humbled Himself to become man. it is a stumbling block for many, the Incarnation. those who reject the Incarnation are dependent upon the teachings of finite men for whatever benefits they imagine they receive. we who accept the Incarnate Word are blessed with graces that cannot be provided by other men who are solely human and are not divine in any real sense of the word.
God became man. without that faith, it is impossible to understand, at least intellectually, any of the divine/heavenly mysteries Jesus revealed.
If Jesus is not fully human and fully divine, then we are still in our sins because we finite creatures have no means at our disposal to make amends for our offenses against Infinite Being.
we who are sinners are not entitled to God’s mercy. we receive it completely freely through the Incarnate Word.
