4822. 'And he called his name Er' means the essential nature of that falsity. This is clear from the meaning of 'calling the name' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006, 3421, namely the nature of the falsity of the Church, dealt with immediately above in 4821. The expression 'the nature of the falsity' is used because falsities differ from one another, even as truths do, so much so that the different types of falsity can hardly be counted; and each type of falsity has its own specific nature by which it is distinguished from any other. Common falsities reign among the wicked in every Church, but each person's falsity varies in keeping with the life he leads. The falsity which existed in the Jewish Church and is referred to here was falsity springing from the evil of self-love and of love of the world based on this, see 4818.

In the same gospel,

These things have been written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name. John 20:31.

And elsewhere. 'His name' means everything in its entirety by which the Lord is worshipped, and so the essential nature of all worship and doctrine, see 2724. Here therefore the good of love and charity is meant when joined to the truth of faith, which constitutes the fabric of doctrine and worship in their entirety.
