One (The Nicene Creed; The Apostles’ Creed, 2.3):
We believe in one holy catholic and apostolic Church,
the communion of saints, the forgiveness of sins;
the resurrection of the body, and the life everlasting.
All (The Scots Confession, 3.01.):
We confess and acknowledge one God alone,
distinct in three persons:
the Father, the Son, and the Holy Ghost,
to whom alone we must cleave,
and in whom alone we put our trust.
