Therefore a person who is divorced and “remarried” is not able to receive the sacrament of Holy Communion, or able to make a spiritual communion, until they repent of their sin.

For those who are in sanctifying grace, here is the prayer...
My Jesus,
I believe that You
are present in the Most Holy Sacrament.
I love You above all things,
and I desire to receive You into my soul.
Since I cannot at this moment
receive You sacramentally,
come at least spiritually into my heart. I embrace You as if You were already there and unite myself wholly to You. Never permit me to be separated from You.
Amen.
