We have been branded in the name of the Trinity, and we acclaim the Father, Son and Spirit again and again.
Every time we make the sign of the cross, we relive our baptism and mark ourselves on behalf of the one God in three persons. We do it at the start of many prayers – and at the start of the greatest prayer, the Mass.
And there is this to remember: we have help. Christ’s concluding statement in the today's Gospel – “I am with you always” – echoes what the angels proclaimed at the time of his birth.
“He will be called Emmanuel. God is with us.”
This Trinity Sunday, we affirm that, and celebrate that.
