I should next show you the modes, or manner, how we should keep the Sabbath day holy; but before I come to that, we have a great question to consider.
'How comes it to pass that we do not keep the seventh-day Sabbath as it was in the primitive institution, but have changed it to another day?'
The old seventh-day Sabbath, which was the Jewish Sabbath, is abrogated, and in the room of it the first day of the week, which is the Christian Sabbath, succeeds. The morality or substance of the fourth commandment does not lie in keeping the seventh day precisely, but keeping one day in seven is what God has appointed.
But how comes the first day in the week to be substituted in the room of the seventh day?
Not by ecclesiastic authority. The church,' says Mr Perkins, has no power to ordain a Sabbath.'
(1) The change of the Sabbath from the last day of the week to the first was by Christ's own appointment. He is Lord of the Sabbath.' Mark 2: 28. And who shall appoint a day but he who is Lord of it? He made this day. This is the day which the Lord has made.' Psa 118: 24. Arnobius and most expositors understand it of the Christian Sabbath, which is called the Lord's-day.' Rev 1: 10. As it is called the Lord's Supper,' because of the Lord's instituting the bread and wine and setting it apart from a common to a special and sacred use; so it is called the Lord's-day, because of the Lord's instituting it, and setting it apart from common days, to his special worship and service. Christ rose on the first day of the week, out of the grave, and appeared twice on that day to his disciples, John 20: 19, 26, which was to intimate to them, as Augustine and Athanasius say, that he transferred the Jewish Sabbath to the Lord's day.
