read Matthew 24.
BTW - the Church is not a “religous institution”, Christians know it is the Body of Christ on earth.
The body of Christ is made up of saved believers. THere is no one in the RCC who claims they are saved, or can even KNOW if they are saved while they are on this earth. So no, the Catholic Church is NOT the Body of Christ on earth.
You are awful loose with that word Christian...And then to imply that it is your religion that is Christian is a mockery of the scriptures...
The scriptures define what the church , the body of Christ is...And sorry, it ain't your (C)hurch...
