St. Paul, we observe, lays great stress upon honesty of conscience. He wishes men, even in small matters, seriously to cultivate a conscience of what is right, as men should do who even in small things expect a divine judgement; and seriously also to cultivate the faculty of not interfering with their brother's conscience. ('Hast thou faith? Have it to thyself.' Do not parade your superior enlightenment.) He is greatly afraid of people leading others, or being led for mere agreement's sake, to do what their own conscience does not justify. And to do even a good thing because another does it whom we want to be like, without ourselves feeling sure it is good, or with a doubtful conscience[26], this, St. Paul says, is sin. This warning we really need to lay to heart in our age, when fashion is such a very strong force in religion. This individual follows that individual and 'supposes it must be all right, as every one seems to do it'; this congregation follows that {152} congregation in adopting a popular practice, without its real basis and justification being considered. But fashion and the influence of members is a great danger in religion. 'Let every man be fully assured in his own mind.' 'Whatever is not of faith is sin[27].' 2. Plainly, when St. Paul wrote his epistles, there was no observance of a Sabbath obligatory upon Christians[28]. But was there none of Sunday? 'The first day of the week' was already 'the Lord's day,' so far as that Christians who could not meet to 'break the bread' every day, met on that day specially to commemorate the death of their risen Lord till He should come again[29]. It was already sufficiently distinctive for St. Paul to name it as the appropriate day for laying by alms for the poor[30]. But these special observances of it were not obligatory. Christians, when they could meet every day, might make their eucharist every day. No such observance of Sunday was yet enjoined as was incompatible with regarding {153} all days of the week alike. Nothing less than this can satisfy St. Paul's words. In principle, as Bishop Lightfoot said[31], 'the kingdom of Christ has no sacred days or seasons, because every time alike is holy.'
