First Reading for Saints Philip and James, Apostles - Daily Catholic Mass Reading

I am reminding you, brothers and sisters, of the Gospel I preached to you, which you indeed received and in which you also stand.

Through it you are also being saved, if you hold fast to the word I preached to you, unless you believed in vain.

For I handed on to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures; that he was buried; that he was raised on the third day in accordance with the Scriptures; that he appeared to Cephas, then to the Twelve. After that, he appeared to more than five hundred brothers and sisters at once, most of whom are still living, though some have fallen asleep.

After that he appeared to James, then to all the Apostles.

Last of all, as to one born abnormally, he appeared to me.
