What are your responses to the allegations that they make?
Gabe, I will take a section of the link and give my best response below. Thank you for sharing.
Specifically, the Bible says he will:
Build the Third Temple (Ezekiel 37:26-28).
He did rebuild the Temple. But it was a spiritual Temple, in the form of the Universal Church, not a physical Temple made of human hands. Not a physical Temple where the priests sacrifice animals, but the Church that offers the daily sacrifice of the Holy Mass.
The Temple to which Ezekiel refers may someday be built in physical Jerusalem, but its spiritual elements already exist in the Church, where prayer, psalms, and liturgy have continued uninterrupted for a couple thousand years now.
I recall a quote from a rabbi who had said that if you wanted to see what the Temple sacrifice was like back when the Temple stood in Jerusalem, go visit a traditional Latin Mass and witness the sacrifice of the Mass in-person.
Gather all Jews back to the Land of Israel (Isaiah 43:5-6).
The Church has gathered the lost remnants of spiritual Israel. Many of the tribes of Israel were lost and scattered. They have gathered in the Church, which draws spiritual adherents from every corner of the Earth.
When the Temple stood, Jews from many nations and surrounding territories would visit the Temple, sometimes every year for the feasts, and others only once in a lifetime if the distance was too far. Today, any person can visit the sacrifice of the Mass in-person at any local Catholic church nearly any day of the week. The Messiah has been gathering in His people.
Usher in an era of world peace, and end all hatred, oppression, suffering and disease. As it says: “Nation shall not lift up sword against nation, neither shall man learn war anymore.” (Isaiah 2:4)
In our physical churches, there is complete serenity, quiet, and peace. There is no violence in our liturgy. The Church operates on a spiritual plane, removed from the secular, material world.
The spiritual world, by contrast to the secular world, is one of complete peace. The Church provides that environment in its churches, monasteries, and convents, where peace reigns supreme. Just visit a Carthusian monastery someday.
As far as ending hatred and oppression, the Church has long stood for values of compassion and charity and seeking to end hatred and oppression in the physical world. Suffering and diseases are many times cured with prayers, and the intercession of saints.
On a spiritual plane, all of these terrible problems are vanquished in heaven, of which the Church is the sole spiritual representative on Earth.
Spread universal knowledge of the God of Israel, which will unite humanity as one. As it says: “God will be King over all the world – on that day, God will be One and His Name will be One” (Zechariah 14:9).
I can think of no other institution other than the Catholic Church that has zealously spread the Word of the Creator to every corner of the earth. This has been done through missionary work, in the building of churches, schools, hospitals, and more.
Maimonides devotes much of his “Guide for the Perplexed” to the fundamental idea that God is incorporeal, meaning that He assumes no physical form. God is eternal, above time. He is infinite, beyond space. He cannot be born, and cannot die.
God is all powerful, and can do whatever it is He wants. If He wants to assume a human form, He can do so. After all, He is God!
God can intervene supernaturally as He did in the Torah for the Jewish people, and suspend natural laws. God performs millions of miracles every single day. He is all-knowing, all powerful, and perfectly capable of assuming human form if He so chooses. This concept is not an affront to God, but rather an acknowledgement of His almighty powers.
Just as water has three forms - liquid, gas, and ice - God can assume any form He so chooses, and still remain God. The Church believes in the Father, the Son, and the Holy Ghost.
The Jews believe in the Holy Ghost as well. In fact, in the Jewish Siddur, every Friday afternoon preceding the Sabbath an Orthodox Jew is instructed to pray from the Song of Songs. In his introductory comments to the Song of Songs, the famous Jewish commentator, Rashi, describes how Solomon was infused with the Holy Spirit. Certainly, Moses was infused with the Holy Spirit, as was Christ.
So, if God can be the Creator, and the Holy Ghost, why can He not be the Christ? Is God somehow incapable of assuming human form if He so chooses? Of course not.
Christ was the Word - the Torah - made flesh. A living, walking Torah.
Throughout the Christian “New Testament,” Jesus contradicts the Torah and states that its commandments are no longer applicable. For example, John 9:14 records that Jesus made a paste in violation of Shabbat, which caused the Pharisees to say (verse 16), “He does not observe Shabbat!”
Christ came to strengthen the Torah, not abolish it. He never violated any Torah laws. In fact, he put “fences around the Torah” to strengthen the Torah and return the Torah to its original spiritual meaning which had been grossly corrupted.
Christ had not a few choice words to say about how the religious leaders of His time that had corrupted God’s words. The New Testament is replete with this tension between Christ and the religious leaders of His time.
