Collect of the Fourth Sunday of Advent (Excita, quaesumus, Domine, potentiam tuam, et veni: et magna nobis virtute succurre)
O Lord, we pray Thee, raise up Thy power, and come, and with great might succor us; that, by the aid of Thy grace, that which is hindered by our sins may be quickened by Thy merciful forgiveness. Who livest and reignest, etc. Amen.
