Jesus said his Church would be “the light of the world.” He then noted that “a city set on a hill cannot be hid” (Matt. 5:14). This means his Church is a visible organization. It must have characteristics that clearly identify it and that distinguish it from other churches. Jesus promised, “I will build my Church and the gates of hell will not prevail against it” (Matt. 16:18). This means that his Church will never be destroyed and will never fall away from him. His Church will survive until his return.
Among the Christian churches, only the Catholic Church has existed since the time of Jesus. Every other Christian church is an offshoot of the Catholic Church.
Any merely human organization with such members would have collapsed early on. The Catholic Church is today the most vigorous church in the world (and the largest, with a billion members: one sixth of the human race), and that is testimony not to the cleverness of the Church’s leaders, but to the protection of the Holy Spirit.

You can believe what you want and blame the Catholic Church or accept the teachings of Jesus and His Church. We are all sinners and the mission of the Catholic church is to lead us to eternal life with God.
You further asserted, " It must have characteristics that clearly identify it and that distinguish it from other churches." Pure demonic deception at work! HIS church, HIS EKKLESIA shines because of HIS Spirit presence int he believers, not because some institution makes bigger or more showy buildings and has bigger and more grandiose rituals. You are promoting the org which pays your room and board, but it is not 'the Church' Jesus established upon profession of faith in HIM (not your org, faith in HIM).
You opined thatr: " Among the Christian churches, only the Catholic Church has existed since the time of Jesus." In your own sentence you show you actually do know there is a differentiation from Christian and organizations. Sadly, you are stuck on the institutionalization meme, unable to break free from your institution to be a member of HIS REAL EKKLESIA ... but from a Catholic Priest, it is expected. Every other Christian church is an offshoot of the Catholic Church. That is the way satan wants you and others to see this. In looking at it from a false start you are then unable to see that it is immaterial if one org generates other orgs. Man-made religion is like that.
You are fond of asserting false axiomsL " Any merely human organization with such members would have collapsed early on." Zoroastrianism has been around longer that your org. Hinduism has been around much longer. You would not give these institutions credulity, so why use this fallacy to try and promote your org?
You commanded (or tried to command), " You can believe what you want and blame the Catholic Church or accept the teachings of Jesus and His Church." Fallacy of the undistributed middle seems top be a favorite with Catholic apologists ... and sirly Catholic prioests. I DO believe and seek to follow what JESUS teaches, but to presume a man made religious org such as Catholiciism has even close to necessary dogma which must be followed so salavation can eventually happen is ARROGANT to the dead spirit core.
So, if folks don't follow your org they get put on racks, boiled in oil, torn asunder, and tortured, as the CATHOLIC CHURCH way to force their salvation? Or is just suffering in your fabricated purgatory enough now? ... Oh that's right, your Catholic Purgatory is ONLY for Catholics! Nice twist that ...
