This is why invoking the intercession of your Guardian Angel is a beneficial way of staying attentive at Mass. Your Guardian Angel is the perfect helper to keep you immersed in the liturgy and is always with you, ready to come to your aid. Your Guardian Angel is there at your side during Mass and ready to help. All we have to do is ask. It is believed that they especially appreciate the invitation to accompany you as you receive Holy Communion. They will never have the opportunity to receive Jesus in the Eucharist and so being with you during that time is a special event.
So, if you are finding yourself distracted or not especially “in” the Mass, pray to your Guardian Angel and he will be there, urging you on and helping you focus on the meeting of Heaven and Earth that is happening right before your eyes!
