again, baptism is not a work. no one can baptize themself.
baptism is done by the Holy Spirit, thru the Church. ( just as happened in Acts 2:38 ) it is done to us, not by us.
a work is something you do. some people incorrectly believe they are saved because they express “faith” in Jesus Christ. they think this work, which they do, saves them.
no, no, no. we are not saved by anything WE DO.
It is a work of the parents on the behalf of an infant.. Someone must change the diaper.. dress them and carry them to the church.. they must make a public affirmation of faith FOR the child.. it is a work.. especially now that the parents must attend classes and mass to have the baby baptized...
It is a work of the parents and the church.. salvation by works
