He served also as Moderator of the Free Church Federal Council of England and Wales and as President of the Baptist Union of Great Britain (1967-68). The Independent Television Authority appointed him as a member of its Religious Advisory Panel, while the Baptists of England recognised his musical talent by making him a member of the Music Advisory Panel and of the Editorial Board of The Baptist Hymn Book, published in 1962.
He was recognised as an effective lecturer and preacher, and was invited to speak in meetings across Europe and North America. In 1965 he was invited to preach in the the meetings of the Baptist World Alliance in Miami Beach, Florida, and travelled from there to speak in various centres in America.

In 1968 Ithel Jones was invited to preach in the 125th Anniversary of Collins Street Baptist Church in Melbourne, Australia.

He died in Melbourne, Australia on 30 December 1980 - two days before his 70th birthday.
In November 1980, a short time before his death, he accepted an invitation to be appointed Principal Emeritus of the Baptist College in Cardiff on his retirement but died before the intention could be realised.
