I am just a cathecumen in my church as I am new to the faith.
He here refers to a catechism commonly used. It is hence a probable conjecture that this Epistle was written, not immediately after the promulgation of the Gospel, but when they had some kind of polity established in the Churches; such as this, that the catechumen made a confession of his faith before he was admitted to baptism. And there were certain primary points on which the pastor questioned the catechumen, as it appears from the various testimonies of the fathers; there was an examination had especially on the creed called the Apostles' Creed. This was the first entrance, as it were, into the church to those who were adults and enlisted under Christ, as they were before alienated from faith in him. This custom the Apostle mentions, because there was a short time fixed for catechumens, during which they were taught the doctrine of religion, as a master instructs his children in the alphabet, in order that he may afterwards advance them to higher things.
