Now mystically, by Martha’s receiving our Lord into her house is represented the Church which now receives the Lord into her heart. Mary her sister, who sat at Jesus’ feet and heard His word, signifies the same Church, but in a future life, where ceasing from labour, and the ministering to her wants, she shall delight in Wisdom alone. But by her complaining that her sister did not help her, occasion is given for that sentence of our Lord, in which he shews that Church to be anxious and troubled about much service, when there is but one thing needful, which is yet attained through the merits of her service; but He says that Mary hath chosen the good part, for through the one the other is reached, which shall not be taken away.
