What is the name of the hyme sung by the choir entering the church in the final scene of the movie mrs miniver

Didn't see the movie, but Onward Christian Soldier:

Onward, Christian soldiers, marching as to war,
with the cross of Jesus going on before.
Christ, the royal Master, leads against the foe;
forward into battle see his banners go!
Refrain:
Onward, Christian soldiers, marching as to war,
with the cross of Jesus going on before.

2. At the sign of triumph Satan's host doth flee;
on then, Christian soldiers, on to victory!
Hell's foundations quiver at the shout of praise;
brothers, lift your voices, loud your anthems raise.
(Refrain)

3. Like a mighty army moves the church of God;
brothers, we are treading where the saints have trod.
We are not divided, all one body we,
one in hope and doctrine, one in charity.
(Refrain)

4. Crowns and thrones may perish, kingdoms rise and wane,
but the church of Jesus constant will remain.
Gates of hell can never gainst that church prevail;
we have Christ's own promise, and that cannot fail.
(Refrain)

5. Onward then, ye people, join our happy throng,
blend with ours your voices in the triumph song.
Glory, laud, and honor unto Christ the King,
this through countless ages men and angels sing.
(Refrain)

Or Children of the Heavenly King:

Children of the heavenly King,
As ye journey, sweetly sing;
Sing your Savior's worthy praise,
Glorious in his works and ways

We are traveling home to God,
In the way the fathers trod;
They are happy now, and we
Soon their happiness shall see.

Lift your eyes, ye sons of light,
Zion's city is in sight:
There our endless home shall be,
There our Lord we soon shall see.

Fear not, brethren; joyful stand
On the borders of your land;
Jesus Christ, your Father's Son,
Bids you undismayed go on.

Lord, obediently we go,
Gladly leaving all below;
Only thou our Leader be;
And we will still follow thee.
