I was reading somewhere where a Bible Christian had asked the question, “Did Jesus attend a Catholic seminary?”
Thinking about that question, I realized that no, He didn’t. Jesus WAS the ORIGINAL Catholic seminary, and the apostles were the original Catholic seminarians. And then the apostles became the next generation Catholic seminaries, and handed down what they had been taught by the original Catholic seminary professor, Jesus Christ, The Son of God.
And that same body of knowledge and teaching has continued to be handed down by the unbroken line of successors of the apostles to this day.
