OUR HOLY OBLIGATION
When I first became a Christian ... I thought that I could do it on my own, by retiring to my rooms and reading theology, and I wouldn't go to the churches and gospel halls; and then later I found that it was the only way of flying your flag; and, of course, I found that this meant being a target. It is extraordinary how inconvenient to your family it becomes for you to get up early to go to church. It doesn't matter so much if you get up early for anything else, but if you get up early to go to church it's very selfish of you and you upset the house. If there is anything in the teaching of the New Testament which is in the nature of a command, it is that you are obliged to take the Sacrament, and you can't do it without going to church.
