Paul expresses his intention (Rom. 15:24, 28) to visit Spain. There is, however, no evidence that he ever carried it into effect, although some think that he probably did so between his first and second imprisonment. (See TARSHISH.)

Romans 15:24
Whensoever I take my journey into Spain, I will come to you: for I trust to see you in my journey, and to be brought on my way thitherward by you, if first I be somewhat filled with your company.
Romans 15:28
When therefore I have performed this, and have sealed to them this fruit, I will come by you into Spain.

1 Macc. 8:3; (Romans 15:24,28) The local designation, Tarshish, representing the Tartessus of the Greeks, probably prevailed until the fame of the Roman wars in that country reached the East, when it was superseded by its classical name. The mere intention of St. Paul to visit Spain (whether he really did visit it is a disputed question. --ED.) implies two interesting facts, viz., the establishment of a Christian community in that country, and that this was done by Hellenistic Jews resident there. The early introduction of Christianity into that country is attested by Irenaeus and Tertullian.
