Harry Ironside was a famous evangelist of a hundred years ago. He published a book called Letters for Roman Catholic Priests. He actually met a Roman Catholic priest on the train, and being a very affable man and a diligent evangelist, he struck up a relationship that led to correspondence. Ironside rightly paid great attention to the issue of Christ as the only intercessor we need.
He wrote,
Those who have confided in Him as their Saviour need no other mediator than Himself, for Jesus is ever available. His heart is as tender as when here on Earth, his love ever flows out to all his own. We need no other intermediary, neither his mother after the flesh, nor any saint or angel to entreat Him on our behalf. He himself abides forever. He is our great all-compassionate High Priest with God. He is our advocate with the Father; He is our one Mediator excluding every other.We must, therefore, not think of saints as superior Christians who offer their merits for us to God, but rather in Paul’s use, and in the Bible’s use, all Christians are saints. When Paul writes to the saints in Ephesus, he is not writing to an exclusive holy club at the top of the church. He is writing to the entirety of the church. This is the way he speaks in all of his letters. He often uses that expression.1
