I don’t think she was self-centered at all. She wanted Jesus, after all, to have the best possible treatment that she, as a hostess, could give.
Martha gets a bum rap IMO while too often people “use” Mary to get out of legitimate things they should be doing, claiming that just ‘sitting’ is 'the better part.
That’s why I love Catholicism because we don’t cherry pick Scriptures.
Later, when Lazarus, brother of Martha and Mary, has died, it is Mary who stays away when Jesus comes to Bethany; Mary who remains ‘in the home’ wrapped up in mourning.
In John 11 we read: On his arrival, Jesus found that Lazarus had already been in the tomb for four days. 18 Now Bethany was less than two miles[
b] from Jerusalem, 19 and many Jews had come to Martha and Mary to comfort them in the loss of their brother. 20 When Martha heard that Jesus was coming, she went out to meet him, but Mary stayed at home.
21 “Lord,” Martha said to Jesus, “if you had been here, my brother would not have died. 22 But I know that even now God will give you whatever you ask.”
23 Jesus said to her, “Your brother will rise again.”
24 Martha answered, “I know he will rise again in the resurrection at the last day.”
25 Jesus said to her, “I am the resurrection and the life. The one who believes in me will live, even though they die; 26 and whoever lives by believing in me will never die. Do you believe this?”
27 “Yes, Lord,” she replied, “I believe that you are the Messiah, the Son of God, who is to come into the world.”
So here we see that Martha has profited and has chosen ‘the better part’, while Mary has, briefly, retreated into temporal grief.
