It is obligatory to attend Holy Mass every Sunday. The Creed is prayed by all the faithful during these Masses.
The articles of the Creed are brief enunciations and specimens of some, and of the chief, of the great mercies vouchsafed to man in the Gospel.
They are truths of pregnant significance, and of direct practical bearing on Christian life and conduct. Such, for instance, obviously is ‘one Baptism for the remission of sins,’ and ‘the resurrection of the body’. Such then must be our profession of ‘catholicity’.
And, thus considered, the two, ‘the Catholic Church’ and ‘the Communion of Saints’, certainly suggest an explanation of each other; the one introducing us to our associates and patrons in heaven, and the other pointing out to us where to find the true teaching and the means of grace on earth.
