"Go, therefore, make disciples of all the nations; baptise them in the name of the Father and of the Son and of the Holy Spirit, and teach them to observe all the commands I gave you."Matthew 28:16-20
In this week's Gospel, Jesus gave the Great Commandment: to go and make disciples of all nations. In this Commandment, he made explicit the role of the Trinity in the Sacrament of Baptism.
There have been instances where Christians who would like to be received into the Catholic Church are told they have to receive the Sacrament of Baptism again.This is because the Trinity was not invoked in their baptisms - making it invalid. However, the Catholic Church also recognises baptisms performed by certain denominations such as Anglicans, Methodists etc as valid because the Trinity was invoked during their baptisms.
The Trinity comes upon us at the moment of our baptisms - opening our souls to the door to Christ and the Church. Let us always thank God for the gift of the Trinity.
