A majority of the board of deacons at First Baptist Church, where President Carter worships here, has recommended against keeping the pastor, the Rev. Charles Trentham, after his contract expires in February.

In their action Wednesday, which must be passed on by the full church membership, the deacons endorsed a church panel's recommendation that raised the issue of Trentham's two divorces and that also questioned his judgment in becoming "involved" with a woman in the congregation.

Although the 26-year-old woman and the 59-year-old pastor reportedly had dated, "no one has ever accused him of any violation of morals," said Frank McAnear, moderator of the church.

The recommendation endorsed 27 to 11 by the deacons, was issued by a majority of the seven-member pastoral staff committee of the 1,000-member church at 16th and O streets NW. A minority also issued a report that said it "found nothing in the pastor's personal life or professional service to warrant or justify termination of his contract." The minority report advocated retaining Trentham. The pastor who is in the last year of his second three-year contract, could not be reached last night for comment.

Action on the deacons' recommendation is expected at the Nov. 28 business meeting of the church.
