The mutual respect for each other's personalities shown in this closest of human relations was characteristic of the entire family, as will be seen later, when the nature of the business connections between Isaac and his brothers has to be considered. Far from weakening the natural ties, or impairing their proper influence, it seems to have strengthened and perfected them. Asked once towards the close of his life how it was that he had never used tobacco in any form, he answered: "Mother forbade it, and that was enough for George and me. I was never ruled in any way but by her affection. That was sufficient." The parallel fact that he never in his life drank a drop of liquor at a bar or at any public place was probably due to a similar injunction. The children were brought up, too, with exceedingly strict ideas about lying and stealing, and all petty vices. Throughout the family there prevailed an extreme severity on such faults. "I have never forgotten," said Father Hecker, "the furious anger of an aunt of mine and the violent beating she gave one of my cousins for stealing a cent from her drawer. That training has had a great and lasting effect upon my character."
In such antecedents and surroundings it is easy to see the source of that abiding confidence in human nature, and that love for the natural virtues which marked Father Hecker's whole career. They had kept his own youth pure. He had been baptized in infancy, however, as the children of orthodox Protestants more commonly were at that period than at present, and in all probability validly, so that one could never positively say that nature in him had ever been unaided by grace in any particular instance. It is the conviction of those who knew him best that he had never been guilty of deliberate mortal sin. One of these writes:
"During all the intimate hours I spent with him, speaking of his past life he _ever once said that he had been a sinner_ in a sense to convey the idea of mortal sin. And on the other hand he said much to the contrary; so much as to leave no manner of doubt on my mind that he had kept his baptismal innocence. He was deeply attached to an edifying and religious mother; he was at hard work before the dawn of sensual passion, and his recreation, even as a boy, was in talking and reading about deep social and philosophical questions, and listening to others on the same themes. He expressly told me that he had never used drink in excess, and that he had never sinned against purity, never was profane, never told a lie; and he certainly never was dishonest.
